v2.2.9 2013-11-25 Timo Sirainen <tss@iki.fi>
+ Full text search indexing can now be done automatically after
saving/copying mails by setting plugin { fts_autoindex=yes }
+ replicator: Added replication_dsync_parameters setting to pass
"doveadm sync" parameters (for controlling what to replicate).
+ Added mail-filter plugin
+ Added liblzma/xz support (zlib_save=xz)
- v2.2.8's improved cache file handling exposed several old bugs
related to fetching mail headers.
- v2.2.7's iostream handling changes were causing some connections
to be disconnected before flushing their output (e.g. POP3 logout
message wasn't being sent)
v2.2.8 2013-11-19 Timo Sirainen <tss@iki.fi>
+ Mail cache lookups work for the mail being saved. This improves
performance by avoiding the need to parse the mail multiple times
when using some plugins (e.g. mail_log).
+ Mail cache works for recently cached data also with in-memory
indexes.
+ imapc: Many performance improvements, especially when working with
dsync. Also added imapc_feature=fetch-headers which allows using
FETCH BODY.PEEK[HEADER.FIELDS (..)] to avoid reading the entire
header.
+ mail_location = ..:FULLDIRNAME=dbox-Mails is the same as
:DIRNAME=dbox-Mails, but it will also be used for
:INDEX and :CONTROL directories. (It should have worked this way
from the beginning, but can't be changed anymore without breaking
existing installations).
- Fixed infinite loop in message parsing if message ends with
"--boundary" and CR (without LF). Messages saved via SMTP/LMTP can't
trigger this, because messages must end with an "LF.". A user could
trigger this for him/herself though.
- lmtp: Client was sometimes disconnected before all the output was
sent to it.
- imap_zlib plugin caused crashes during client disconnection in
v2.2.7
- replicator: Database wasn't being exported to disk every 15 minutes
as it should have. Instead it was being imported, causing "doveadm
replicator remove" commands to not work very well.
v2.2.7 2013-11-03 Timo Sirainen <tss@iki.fi>
* Some usage of passdb checkpassword could have been exploitable by
local users. You may need to modify your setup to keep it working.
See http://wiki2.dovecot.org/AuthDatabase/CheckPassword#Security
+ auth: Added ability to truncate values logged by
auth_verbose_passwords (see 10-logging.conf comment)
+ mdbox: Added "mdbox_deleted" storage, which can be used to access
messages with refcount=0. For example: doveadm import
mdbox_deleted:~/mdbox "" mailbox inbox subject oops
+ ssl-params: Added ssl_dh_parameters_length setting.
- master process was doing a hostname.domain lookup for each created
process, which may have caused a lot of unnecessary DNS lookups.
- dsync: Syncing over 100 messages at once caused problems in some
situations, causing messages to get new UIDs.
- fts-solr: Different Solr hosts for different users didn't work.
v2.2.6 2013-09-25 Timo Sirainen <tss@iki.fi>
* acl: If public/shared namespace has a shared subscriptions file for
all users, don't list subscription entries that are not visible to
the user accessing it.
+ doveadm: Added "auth lookup" command for doing passdb lookup.
+ login_log_format_elements: Added %{orig_user}, %{orig_username}
and %{orig_domain} expanding to the username exactly as sent by
the client (before any changes auth process made).
+ Added ssl_prefer_server_ciphers setting.
+ auth_verbose_passwords: Log the password also for unknown users.
+ Linux: Added optional support for SO_REUSEPORT with
inet_listener { reuse_port=yes }
- director: v2.2.5 changes caused "SYNC lost" errors
- dsync: Many fixes and error handling improvements
- doveadm -A: Don't waste CPU by doing a separate config lookup
for each user
- Long-running ssl-params process no longer prevents Dovecot restart
- mbox: Fixed mailbox_list_index=yes to work correctly
v2.2.5 2013-08-05 Timo Sirainen <tss@iki.fi>
+ SSL: Added support for ECDH/ECDHE cipher suites (by David Hicks)
+ Added some missing man pages (by Pascal Volk)
+ quota-status: Added quota_status_toolarge setting (by Ulrich Zehl)
- director: Users near expiration could have been redirected to
different servers at the same time.
- pop3: Avoid assert-crash if client disconnects during LIST.
- mdbox: Corrupted index header still wasn't automatically fixed.
- dsync: Various fixes to work better with imapc and pop3c storages.
- ldap: sasl_bind=yes caused crashes, because Dovecot's lib-sasl
symbols conflicted with Cyrus SASL library.
- imap: Various error handling fixes to CATENATE. (Found using
Apple's stress test script.)
v2.2.4 2013-06-25 Timo Sirainen <tss@iki.fi>
+ doveadm: Added "flags" command to modify message flags.
+ doveadm: Added "deduplicate" command to expunge message duplicates.
+ dsync: Show the state in process title with verbose_proctitle=yes.
- imap/pop3 proxy: Master user logins were broken in v2.2.3
- sdbox/mdbox: A corrupted index header with wrong size was never
automatically fixed in v2.2.3.
- mbox: Fixed assert-crashes related to locking.
v2.2.3 2013-06-17 Timo Sirainen <tss@iki.fi>
* LDA/LMTP: If new mail delivery first fails with "temporary
failure", tempfail the whole delivery instead of falling back to
delivering the mail to INBOX. (Requires new Pigeonhole as well.)
* doc/solr-schema.xml was updated to Solr v4.x format. Also the
default analyzers were changed, hopefully for the better. Note that
the schema can't be changed for existing Solr indexes without
rebuilding everything.
* Solr plugin does only soft commits from now on. You'll need a
cronjob to send a hard commit command to it every few minutes.
+ Added %N modifier for variables as %H-like "new hash"
+ sdbox, mdbox: Support POP3 message order field (for migrations)
+ Added mailbox { driver } to specify a different mail storage
format for the mailbox than generally used within the namespace.
+ Added initial lib-sasl library for client side SASL support.
Currently supports only PLAIN, LOGIN and plugins. Used currently
by IMAP and POP3 proxying when authenticating to the remote server.
- IMAP: If subject contained only whitespace, Dovecot returned an
ENVELOPE reply with a huge literal value, effectively causing the
IMAP client to wait for more data forever.
- IMAP: Various URLAUTH fixes.
- imapc: Various bugfixes and improvements
- pop3c: Various fixes to make it work in dsync (without imapc)
- dsync: Fixes to syncing subscriptions. Fixes to syncing mailbox
renames.
v2.2.2 2013-05-20 Timo Sirainen <tss@iki.fi>
+ zlib: Keep the last mail cached uncompressed in a temp file. This
fixes performance when doing small partial fetches from a large
mail.
+ acl: If plugin { acl_defaults_from_inbox = yes } is set, get the
default ACLs for private and shared namespaces from the user's INBOX.
(This probably will become default in v2.3.)
+ pop3: Added pop3_deleted_flag setting to switch POP3 deletions to
only hide the messages from POP3, but still be visible via IMAP.
- ACL plugin: Mailbox creation wasn't actually checking any ACLs
and always succeeded (due to some v2.2 API changes). The created
mailbox couldn't have been accessed though, so this couldn't have
caused any data leak.
- IMAP: Various URLAUTH fixes.
- IMAP: Fixed a hang with invalid APPEND parameters.
- IMAP LIST-EXTENDED: INBOX was never listed with \Subscribed flag.
- mailbox_list_index=yes still caused crashes.
- maildir: Fixed a crash after dovecot-keywords file was re-read.
- maildir: If files had reappeared unexpectedly to a Maildir, they
were ignored until index files were deleted.
- Maildir: Fixed handling over 26 keywords in a mailbox.
- Maildir++: Fixed mail_shared_explicit_inbox=no
- namespace { prefix="" list=no } was listing mailboxes.
- imap/pop3-login proxying: Fixed a crash if TCP connection succeeded,
but the remote login timed out.
- Case-insensitive search/sort didn't work correctly for all unicode
characters, as specified by i;unicode-casemap comparator. If full
text search indexes were used, they need to be rebuilt for old mails
to be handled correctly. (This bug has existed always in Dovecot.)
v2.2.1 2013-04-19 Timo Sirainen <tss@iki.fi>
- mailbox_list_index=yes was broken.
- LAYOUT=index didn't list subscriptions.
- auth: Multiple master passdbs didn't work.
- Message parsing (e.g. during search) crashed when multipart message
didn't actually contain any parts.
v2.2.0 2013-04-11 Timo Sirainen <tss@iki.fi>
* When creating home directories, the permissions are copied from the
parent directory if it has setgid-bit set. For full details, see
http://wiki2.dovecot.org/SharedMailboxes/Permissions
* "doveadm auth" command was renamed to "doveadm auth test"
* IMAP: ID command now advertises server name as Dovecot by default.
It was already trivial to guess this from command replies.
* dovecot.index.cache files can be safely accessed only by v2.1.11+.
Older versions may think they're corrupted and delete them.
* LDA/LMTP: If saving a mail brings user from under quota to over
quota, allow it based on quota_grace setting (default: 10%
above quota limit).
* pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock
file instead of actually locking the mailbox (and causing
IMAP/LDA/LMTP to wait for the POP3 session to close).
* mail_shared_explicit_inbox setting's default switched to "no".
* ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and
pop3c_ssl_ca_dir settings.
+ Implemented IMAP MOVE and BINARY extensions
+ Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions
(by Stephan Bosch).
+ Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes
to be enabled.
+ Redesigned and rewritten dsync. The new design makes the syncing
faster, more reliable and more featureful. The new dsync protocol
isn't backwards compatible with old dsync versions (but is designed
to be forwards compatible with future versions).
+ All mailbox formats now support per-user message flags for shared
mailboxes by using a private index. It can be enabled by adding
:INDEXPVT=<path> to mail location. This should be used instead of
:INDEX also for Maildir/mbox to improve performance.
+ Improved mailbox list indexes. They should be usable now, although
still disabled by default.
+ Added LAYOUT=index. The mailbox directories are created using their
GUIDs in the filesystem, while the actual GUID <-> name mapping
exists only in the index.
+ LMTP proxy: Implemented XCLIENT extension for passing remote IP
address through proxy.
v2.2.rc7 2013-04-10 Timo Sirainen <tss@iki.fi>
* checkpasword: AUTH_PASSWORD environment is no longer set.
* Running dsync no longer triggers quota warnings.
+ dsync: Commit large transactions every 100 new messages, so if a
large sync crashes it doesn't have to be restarted from the
beginning.
- replicator: doveadm commands and user list export may have skipped
some users.
- Various fixes to mailbox_list_index=yes
v2.2.rc6 2013-04-08 Timo Sirainen <tss@iki.fi>
* replicator: Don't create replicator-doveadm socket by default.
This way doveadm replicator commands don't accidentally start an
unconfigured replicator server.
+ replicator: Have remote dsync notify the remote replicator that
a user was just synced. This way the replicators are kept roughly
in sync.
+ Added ssl_client_ca_file to specify the CA certs as a file. This is
needed (instead of ssl_client_ca_dir) in RedHat-based systems.
+ Added "doveadm fs" commands, mainly to debug lib-fs backends.
- Mailbox list indexes weren't using proper file permissions based
on the root directory.
v2.2.rc5 2013-04-05 Timo Sirainen <tss@iki.fi>
- A few small random fixes
v2.2.rc4 2013-04-05 Timo Sirainen <tss@iki.fi>
+ Added "doveadm replicator" commands
- Larger changes to lib-http and lib-ssl-iostream error handling.
The API caller can now get the exact error message as a string.
- Various bugfixes to LDAP changes in rc3
v2.2.rc3 2013-03-20 Timo Sirainen <tss@iki.fi>
+ dsync: Support syncing ACLs (and Sieve scripts with Pigeonhole)
+ ldap: Support subqueries and value pointers, see
http://wiki2.dovecot.org/AuthDatabase/LDAP/Userdb
+ postmaster_address setting: Expand %d to recipient's domain
- Fixed a crash when decoding quoted-printable content.
- dsync: Various bugfixes
v2.2.rc2 2013-02-15 Timo Sirainen <tss@iki.fi>
- rc1 wasn't actually usable in most configurations.
v2.2.rc1 2013-02-15 Timo Sirainen <tss@iki.fi>
* See v2.2.0 notes
v2.1.13 2013-01-06 Timo Sirainen <tss@iki.fi>
- Some fixes to cache file changes in v2.1.11.
- fts-solr: Overlong UTF8 sequences in mails were rejected by Solr and
caused the mails to not be indexed.
- virtual storage: Sorting mailbox by from/to/cc/bcc didn't work.
v2.1.12 2012-11-30 Timo Sirainen <tss@iki.fi>
- dovecot-config in v2.1.11 caused build problems with Pigeonhole
v2.1.11 2012-11-29 Timo Sirainen <tss@iki.fi>
* lmtp/lda: dovecot.index.cache file is no longer fully mapped to
memory, allowing mail deliveries to work even if the file is huge.
* auth: userdb passwd lookups are now done by auth worker processes
instead of auth master process (as it was documented, but
accidentally didn't work that way).
+ lmtp: lmtp_rcpt_check_quota=yes setting checks quota on RCPT TO.
- lmtp: After successful proxying RCPT TO, the next one to a
nonexistent user gave tempfail error instead of "user not found".
- lmtp proxy: Fixed hanging if remote server was down.
- imap: Fixed crash when SEARCH contained multiple KEYWORD parameters.
- doveadm: Various fixes to handling doveadm-server connections.
- -i <instance name> parameter for Dovecot tools didn't work correctly.
- director was somewhat broken in v2.1.10. This version also includes
various reliability enhancements.
- auth: passdb imap was broken in v2.1.10.
v2.1.10 2012-09-18 Timo Sirainen <tss@iki.fi>
+ imap: Implemented THREAD=ORDEREDSUBJECT extension.
+ Added "doveadm exec" command to easily execute commands from
libexec_dir, e.g. "doveadm exec imap -u user@domain"
+ Added "doveadm copy" command.
+ doveadm copy/move: Added optional user parameter to specify the
source username. This allows easily copying mails between different
users.
+ Added namespace { disabled } setting to quickly enable/disable
namespaces. This is especially useful when its value is returned by
userdb.
+ Added mailbox_alias plugin. It allows creating mailbox aliases using
symlinks.
+ imapc storage: Added imapc_max_idle_time setting to force activity
on connection.
+ fts-solr: Expunging multiple messages is now faster.
- director: In some conditions director may have disconnected from
another director (without logging about it), thinking it was sending
invalid data.
- imap: Various fixes to listing mailboxes.
- pop3-migration plugin: Avoid disconnection from POP3 server due
to idling.
- login processes crashed if there were a lot of local {} or remote {}
settings blocks.
v2.1.9 2012-08-01 Timo Sirainen <tss@iki.fi>
* mail-log plugin: Log mailbox names with UTF-8 everywhere
(instead of mUTF-7 in some places and UTF-8 in other places)
* director: Changed director_username_hash setting's default from %u
to %Lu (= lowercase usernames). This doesn't break any existing
installations, but might fix some of them.
+ doveadm: Added "auth cache flush [<username>]" command.
+ Implemented dict passdb/userdb
+ Implemented Redis and memcached dict backends, which can be used as
auth backends. Redis can also be used as dict-quota backend.
+ Added plugin { quota_ignore_save_errors=yes } setting to allow saving
a mail when quota lookup fails with temporary failure.
- Full text search indexing might have failed for some messages,
always causing indexer-worker process to run out of memory.
- fts-lucene: Fixed handling SEARCH HEADER FROM/TO/SUBJECT/CC/BCC when
the header wasn't lowercased.
- fts-squat: Fixed crash when searching a virtual mailbox.
- pop3: Fixed assert crash when doing UIDL on empty mailbox on some
setups.
- auth: GSSAPI RFC compliancy and error handling fixes.
- Various fixes related to handling shared namespaces
v2.1.8 2012-07-03 Timo Sirainen <tss@iki.fi>
+ pop3c: Added pop3c_master_user setting.
- imap: Mailbox names were accidentally sent as UTF-8 instead of mUTF-7
in previous v2.1.x releases for STATUS, MYRIGHTS and GETQUOTAROOT
commands.
- lmtp proxy: Don't timeout connections too early when mail has a lot
of RCPT TOs.
- director: Don't crash if the director is working alone.
- shared mailboxes: Avoid doing "@domain" userdb lookups.
- doveadm: Fixed crash with proxying some commands.
- fts-squat: Fixed handling multiple SEARCH parameters.
- imapc: Fixed a crash when message had more than 8 keywords.
- imapc: Don't crash on APPEND/COPY if server doesn't support UIDPLUS.
v2.1.7 2012-05-29 Timo Sirainen <tss@iki.fi>
* LDAP: Compatibility fix for v2.0: ldap: If attributes contain
ldapAttr=key=template%$ and ldapAttr doesn't exist, skip the key
instead of using "template" value with empty %$ part for the key.
+ pop3: Added pop3_uidl_duplicates setting for changing the behavior
for duplicate UIDLs.
+ director: Added "doveadm director ring remove" command.
- director: Don't crash with quickly disconnecting incoming director
connections.
- mdbox: If mail was originally saved to non-INBOX, and namespace
prefix is non-empty, don't assert-crash when rebuilding indexes.
- sdbox: Don't use more fds than necessary when copying mails.
- auth: Fixed crash with DIGEST-MD5 when attempting to do master user
login without master passdbs.
- Several fixes to mail_shared_explicit_inbox=no
- imapc: Use imapc_list_prefix also for listing subscriptions.
v2.1.6 2012-05-07 Timo Sirainen <tss@iki.fi>
* Session ID is now included by default in auth and login process
log lines. It can be added to mail processes also by adding
%{session} to mail_log_prefix.
+ Added ssl_require_crl setting, which specifies if CRL check must
be successful when verifying client certificates.
+ Added mail_shared_explicit_inbox setting to specify if a shared INBOX
should be accessible as "shared/$user" or "shared/$user/INBOX".
- v2.1.5: Using "~/" as mail_location or elsewhere failed to actually
expand it to home directory.
- dbox: Fixed potential assert-crash when reading dbox files.
- trash plugin: Fixed behavior when quota is already over limit.
- mail_log plugin: Logging "copy" event didn't work.
- Proxying to backend server with SSL: Verifying server certificate
name always failed, because it was compared to an IP address.
v2.1.5 2012-04-23 Timo Sirainen <tss@iki.fi>
* IMAP: When neither the session nor the mailbox has modseq tracking
enabled, return the mailbox as having NOMODSEQ in SELECT/EXAMINE
reply. Old versions in this situation always simply returned
HIGHESTMODSEQ as 1, which could have broken some clients.
+ dict file: Added optional fcntl/flock locking (default is dotlock)
+ fts-solr: doveadm fts rescan now resets indexes, which allows
reindexing mails. (This isn't a full rescan implementation like
fts-lucene has.)
+ doveadm expunge: Added -d parameter to delete mailbox if it's
empty after expunging.
- IMAP: Several fixes related to mailbox listing in some configs
- director: A lot of fixes and performance improvements
- v2.1.4 didn't work without a mail home directory set
- mbox: Deleting a mailbox didn't delete its index files.
- pop3c: TOP command was sent incorrectly
- trash plugin didn't work properly
- LMTP: Don't add a duplicate Return-Path: header when proxying.
- listescape: Don't unescape namespace prefixes.
v2.1.4 2012-04-09 Timo Sirainen <tss@iki.fi>
+ Added mail_temp_scan_interval setting and changed its default value
from 8 hours to 1 week.
+ Added pop3-migration plugin for easily doing a transparent IMAP+POP3
migration to Dovecot: http://wiki2.dovecot.org/Migration/Dsync
+ doveadm user: Added -m parameter to show some of the mail settings.
- Proxying SSL connections crashed in v2.1.[23]
- fts-solr: Indexing mail bodies was broken.
- director: Several changes to significantly improve error handling
- doveadm import didn't import messages' flags
- mail_full_filesystem_access=yes was broken
- Make sure IMAP clients can't create directories when accessing
nonexistent users' mailboxes via shared namespace.
- Dovecot auth clients authenticating via TCP socket could have failed
with bogus "PID already in use" errors.
v2.1.3 2012-03-16 Timo Sirainen <tss@iki.fi>
- mdbox was broken in v2.1.2
v2.1.2 2012-03-15 Timo Sirainen <tss@iki.fi>
+ Initial implementation of dsync-based replication. For now this
should be used only on non-critical systems.
+ Proxying: POP3 now supports sending remote IP+port from proxy to
backend server via Dovecot-specific XCLIENT extension.
+ Proxying: proxy_maybe=yes with host=<hostname> (instead of IP)
works now properly.
+ Proxying: Added auth_proxy_self setting
+ Proxying: Added proxy_always extra field (see wiki docs)
+ Added director_username_hash setting to specify what part of the
username is hashed. This can be used to implement per-domain
backends (which allows safely accessing shared mailboxes within
domain).
+ Added a "session ID" string for imap/pop3 connections, available
in %{session} variable. The session ID passes through Dovecot
IMAP/POP3 proxying to backend server. The same session ID is can be
reused after a long time (currently a bit under 9 years).
+ passdb checkpassword: Support "credentials lookups" (for
non-plaintext auth and for lmtp_proxy lookups)
+ fts: Added fts_index_timeout setting to abort search if indexing
hasn't finished by then (default is to wait forever).
- doveadm sync: If mailbox was expunged empty, messages may have
become back instead of also being expunged in the other side.
- director: If user logged into two directors while near user
expiration, the directors might have redirected the user to two
different backends.
- imap_id_* settings were ignored before login.
- Several fixes to mailbox_list_index=yes
- Previous v2.1.x didn't log all messages at shutdown.
- mbox: Fixed accessing Dovecot v1.x mbox index files without errors.
v2.1.1 2012-02-23 Timo Sirainen <tss@iki.fi>
+ dsync: If message with same GUID is saved multiple times in session,
copy it instead of re-saving.
- acl plugin + autocreated mailboxes crashed when listing mailboxes
- doveadm force-resync: Don't skip autocreated mailboxes (especially
INBOX).
- If process runs out of fds, stop listening for new connections only
temporarily, not permanently (avoids hangs with process_limit=1
services)
- auth: passdb imap crashed for non-login authentication (e.g. smtp).
v2.1.0 2012-02-16 Timo Sirainen <tss@iki.fi>
* Plugins now use UTF-8 mailbox names rather than mUTF-7:
acl, autocreate, expire, trash, virtual
* auth_username_format default changed to %Lu. If you really want
case sensitive usernames, set it back to empty.
* Solr full text search backend changed to use mailbox GUIDs instead of
mailbox names, requiring reindexing everything. solr_old backend can
be used with old indexes to avoid reindexing, but it doesn't support
some newer features.
* Expire plugin: Only go through users listed by userdb iteration.
Delete dict rows for nonexistent users, unless
expire_keep_nonexistent_users=yes.
* Temporary authentication failures sent to IMAP/POP3 clients
now includes the server's hostname and timestamp. This makes it
easier to find the error message from logs.
* dsync was merged into doveadm. There is still "dsync" symlink
pointing to "doveadm", which you can use the old way for now.
The preferred ways to run dsync are "doveadm sync" (for old "dsync
mirror") and "doveadm backup".
+ imapc (= IMAP client) storage allows using a remote IMAP server to
be used as storage. This allows using Dovecot as a smart (caching)
proxy or using dsync to do migration from remote IMAP server.
+ Mailbox indexing via queuing indexer service (required for Lucene)
+ Lucene full text search (FTS) backend rewritten with support for
different languages
+ FTS finally supports "OR" search operation
+ FTS supports indexing attachments via external programs
+ IMAP FUZZY extension, supported by Lucene and Solr FTS backends
+ IMAP SPECIAL-USE extension to describe mailboxes
+ Mailbox list indexes
+ Statistics tracking via stats service. Exported via doveadm stats.
+ Autocreate plugin creates/subscribes mailboxes physically only when
the mailbox is opened for the first time. Mailbox listing shows the
autocreated mailboxes even if they don't physically exist.
+ Password and user databases now support default_fields and
override_fields settings to specify template defaults/overrides.
+ SCRAM-SHA-1 authentication mechanism by Florian Zeitz
+ LDAP: Allow building passdb/userdb extra fields from multiple LDAP
attributes by using %{ldap:attributeName} variables in the template.
+ Improved multi-instance support: Track automatically which instances
are started up and manage the list with doveadm instance commands.
All Dovecot commands now support -i <instance_name> parameter to
select the instance (instead of having to use -c <config path>).
See instance_name setting.
+ auth: Implemented support for Postfix's "TCP map" sockets for
user existence lookups.
- listescape plugin works perfectly now
v2.1.rc7 2012-02-15 Timo Sirainen <tss@iki.fi>
+ Added ignore_on_failure setting for namespaces. If namespace
initialization fails with this enabled (e.g. permission denied),
the namespace is silently skipped for the user.
v2.1.rc6 2012-02-12 Timo Sirainen <tss@iki.fi>
* Added automatic mountpoint tracking and doveadm mount commands to
manage the list. If a mountpoint is unmounted, error handling is
done by assuming that the files are only temporarily lost. This is
especially helpful if dbox alt storage becomes unmounted.
* Expire plugin: Only go through users listed by userdb iteration.
Delete dict rows for nonexistent users, unless
expire_keep_nonexistent_users=yes.
* LDA's out-of-quota and Sieve's reject mails now include DSN report
instead of MDN report.
+ LDAP: Allow building passdb/userdb extra fields from multiple LDAP
attributes by using %{ldap:attributeName} variables in the template.
+ doveadm log errors shows the last 1000 warnings and errors since
Dovecot was started.
+ Improved multi-instance support: Track automatically which instances
are started up and manage the list with doveadm instance commands.
All Dovecot commands now support -i <instance_name> parameter to
select the instance (instead of having to use -c <config path>).
See instance_name setting.
+ doveadm mailbox delete: Added -r parameter to delete recursively
+ doveadm acl: Added "add" and "remove" commands.
+ Updated to Unicode v6.1
- mdbox: When saving to alt storage, Dovecot didn't append as much
data to m.* files as it could have.
- dbox: Fixed error handling when saving failed or was aborted
- IMAP: Using COMPRESS extension may have caused assert-crashes
- IMAP: THREAD REFS sometimes returned invalid (0) nodes.
- dsync: Fixed handling non-ASCII characters in mailbox names.
v2.1.rc5 2012-01-26 Timo Sirainen <tss@iki.fi>
* Temporary authentication failures sent to IMAP/POP3 clients
now includes the server's hostname and timestamp. This makes it
easier to find the error message from logs.
+ auth: Implemented support for Postfix's "TCP map" sockets for
user existence lookups.
+ auth: Idling auth worker processes are now stopped. This reduces
error messages about MySQL disconnections.
- director: With >2 directors ring syncing might have stalled during
director connect/disconnect, causing logins to fail.
- LMTP client/proxy: Fixed potential hanging when sending (big) mails
- Compressed mails with external attachments (dbox + SIS + zlib) failed
sometimes with bogus "cached message size wrong" errors.
v2.1.rc4 was never actually released, but was accidentally tagged in hg.
v2.1.rc3 2012-01-06 Timo Sirainen <tss@iki.fi>
- Added missing file that prevented v2.1.rc2 from compiling..
v2.1.rc2 2012-01-06 Timo Sirainen <tss@iki.fi>
* dsync was merged into doveadm. There is still "dsync" symlink
pointing to "doveadm", which you can use the old way for now.
The preferred ways to run dsync are "doveadm sync" (for old "dsync
mirror") and "doveadm backup".
+ IMAP SPECIAL-USE extension to describe mailboxes
+ Added mailbox {} sections, which deprecate autocreate plugin
+ lib-fs: Added "mode" parameter to "posix" backend to specify mode
for created files/dirs (for mail_attachment_dir).
+ inet_listener names are now used to figure out what type the socket
is when useful. For example naming service auth { inet_listener } to
auth-client vs. auth-userdb has different behavior.
+ Added pop3c (= POP3 client) storage backend.
- LMTP proxying code was simplified, hopefully fixing its problems.
- dsync: Don't remove user's subscriptions for subscriptions=no
namespaces.
v2.1.rc1 2011-11-24 Timo Sirainen <tss@iki.fi>
* Plugins now use UTF-8 mailbox names rather than mUTF-7:
acl, autocreate, expire, trash, virtual
* auth_username_format default changed to %Lu. If you really want
case sensitive usernames, set it back to empty.
* Solr full text search backend changed to use mailbox GUIDs instead of
mailbox names, requiring reindexing everything. solr_old backend can
be used with old indexes to avoid reindexing, but it doesn't support
some newer features.
+ imapc (= IMAP client) storage allows using a remote IMAP server to
be used as storage. This allows using Dovecot as a smart (caching)
proxy or using dsync to do migration from remote IMAP server.
+ Mailbox indexing via queuing indexer service (required for Lucene)
+ Lucene full text search (FTS) backend rewritten with support for
different languages
+ FTS finally supports "OR" search operation
+ FTS supports indexing attachments via external programs
+ IMAP FUZZY extension, supported by Lucene and Solr FTS backends
+ IMAP SPECIAL-USE extension to describe mailboxes
+ Mailbox list indexes
+ Statistics tracking via stats service. Exported via doveadm stats.
+ Autocreate plugin creates/subscribes mailboxes physically only when
the mailbox is opened for the first time. Mailbox listing shows the
autocreated mailboxes even if they don't physically exist.
+ Password and user databases now support default_fields and
override_fields settings to specify template defaults/overrides.
+ SCRAM-SHA-1 authentication mechanism by Florian Zeitz
- listescape plugin works perfectly now
v2.0.15 2011-09-16 Timo Sirainen <tss@iki.fi>
+ doveadm altmove: Added -r parameter to move mails back to primary
storage.
- v2.0.14: Index reading could have eaten a lot of memory in some
situations
- doveadm index no longer affects future caching decisions
- mbox: Fixed crash during mail delivery when mailbox didn't yet have
GUID assigned to it.
- zlib+mbox: Fetching last message from compressed mailboxes crashed.
- lib-sql: Fixed load balancing and error handling when multiple hosts
are used.
v2.0.14 2011-08-29 Timo Sirainen <tss@iki.fi>
+ doveadm: Added support for running mail commands by proxying to
another doveadm server.
+ Added "doveadm proxy list" and "doveadm proxy kick" commands to
list/kick proxy connections (via a new "ipc" service).
+ Added "doveadm director move" to assign user from one server to
another, killing any existing connections.
+ Added "doveadm director ring status" command.
+ userdb extra fields can now return name+=value to append to an
existing name, e.g. "mail_plugins+= quota".
- script-login attempted an unnecessary config lookup, which usually
failed with "Permission denied".
- lmtp: Fixed parsing quoted strings with spaces as local-part for
MAIL FROM and RCPT TO.
- imap: FETCH BODY[HEADER.FIELDS (..)] may have crashed or not
returned all data sometimes.
- ldap: Fixed random assert-crashing with with sasl_bind=yes.
- Fixes to handling mail chroots
- Fixed renaming mailboxes under different parent with FS layout when
using separate ALT, INDEX or CONTROL paths.
- zlib: Fixed reading concatenated .gz files.
v2.0.13 2011-05-11 Timo Sirainen <tss@iki.fi>
+ Added "doveadm index" command to add unindexed messages into
index/cache. If full text search is enabled, it also adds unindexed
messages to the fts database.
+ added "doveadm director dump" command.
+ pop3: Added support for showing messages in "POP3 order", which can
be different from IMAP message order. This can be useful for
migrations from other servers. Implemented it for Maildir as 'O'
field in dovecot-uidlist.
- doveconf: Fixed a wrong "subsection has ssl=yes" warning.
- mdbox purge: Fixed wrong warning about corrupted extrefs.
- sdbox: INBOX GUID changed when INBOX was autocreated, leading to
trouble with dsync.
- script-login binary wasn't actually dropping privileges to the
user/group/chroot specified by its service settings.
- Fixed potential crashes and other problems when parsing header names
that contained NUL characters.
v2.0.12 2011-04-12 Timo Sirainen <tss@iki.fi>
+ doveadm: Added "move" command for moving mails between mailboxes.
+ virtual: Added support for "+mailbox" entries that clear \Recent
flag from messages (default is to preserve them).
- dbox: Fixes to handling external attachments
- dsync: More fixes to avoid hanging with remote syncs
- dsync: Many other syncing/correctness fixes
- doveconf: v2.0.10 and v2.0.11 didn't output plugin {} section right
v2.0.11 2011-03-07 Timo Sirainen <tss@iki.fi>
* dotlock_use_excl setting's default was accidentally "no" in all
v2.0.x releases, instead of "yes" as in v1.1 and v1.2. Changed it
back to "yes."
- v2.0.10: LDAP support was broken
- v2.0.10: dsyncing to remote often hanged (timed out in 15 mins)
v2.0.10 2011-03-04 Timo Sirainen <tss@iki.fi>
* LMTP: For user+detail@domain deliveries, the +detail is again written
to Delivered-To: header.
* Skip auth penalty checks from IPs in login_trusted_networks.
+ Added import_environment setting.
+ Added submission_host setting to send mails via SMTP instead of
via sendmail binary.
+ Added doveadm acl get/set/delete commands for ACL manipulation,
similar to how IMAP ACL extension works.
+ Added doveadm acl debug command to help debug and fix problems
with why shared mailboxes aren't working as expected.
- IMAP: Fixed hangs with COMPRESS extension
- IMAP: Fixed a hang when trying to COPY to a nonexistent mailbox.
- IMAP: Fixed hang/crash with SEARCHRES + pipelining $.
- IMAP: Fixed assert-crash if IDLE+DONE is sent in same TCP packet.
- LMTP: Fixed sending multiple messages in a session.
- doveadm: Fixed giving parameters to mail commands.
- doveadm import: Settings weren't correctly used for the
import storage.
- dsync: Fixed somewhat random failures with saving messages to
remote dsync.
- v2.0.9: Config reload didn't notify running processes with
shutdown_clients=no, so they could have kept serving new clients
with old settings.
v2.0.9 2011-01-13 Timo Sirainen <tss@iki.fi>
- Linux: Fixed a high system CPU usage / high context switch count
performance problem
- Maildir: Avoid unnecessarily reading dovecot-uidlist while opening
mailbox.
- Maildir: Fixed renaming child mailboxes when namespace had a prefix.
- mdbox: Don't leave partially written messages to mdbox files when
aborting saving.
- Fixed master user logins when using userdb prefetch
- lda: Fixed a crash when trying to send "out of quota" reply
- lmtp: If delivering duplicate messages to same user's INBOX,
create different GUIDs for them. This helps to avoid duplicate
POP3 UIDLs when pop3_uidl_format=%g.
- virtual storage: Fixed saving multiple mails in a transaction
(e.g. copy multiple messages).
- dsync: Saved messages' save-date was set to 1970-01-01.
v2.0.8 2010-12-03 Timo Sirainen <tss@iki.fi>
* Services' default vsz_limits weren't being enforced correctly in
earlier v2.0 releases. Now that they are enforced, you might notice
that the default limits are too low and you need to increase them.
This problem will show up in logs as "out of memory" errors.
See default_vsz_limit and service { vsz_limit } settings.
* LMTP: In earlier versions if mail was delivered to user+detail@domain
address, LMTP server always attempted to deliver the mail to mailbox
named "detail". This was rather unintentional and shouldn't have been
the default. lmtp_save_to_detail_mailbox=yes setting now preserves
this behavior (default is no).
+ Added systemd support (configure --with-systemdsystemunitdir).
Based on patch by Christophe Fergeau.
+ Replaced broken mbox-snarf plugin with a new more generic snarf
plugin.
- dbox: Fixes to handling external mail attachments
- verbose_proctitle=yes didn't work for all processes in v2.0.7
- imap, pop3: When service { client_count } was larger than 1, the
log messages didn't use the correct prefix. Last logged in user's
prefix was always used, regardless of what user's session actually
logged it. Now the proper log prefix is always used.
- MySQL: Only the first specified host was ever used
v2.0.7 2010-11-08 Timo Sirainen <tss@iki.fi>
* master: default_process_limit wasn't actually used anywhere,
rather the default was unlimited. Now that it is enforced, you might
notice that the default limit is too low and you need to increase it.
Dovecot logs a warning when this happens.
* mail-log plugin: Log mailbox name as virtual name rather than
physical name (e.g. namespace prefix is included in the name)
+ doveadm dump: Added imapzlib type to uncompress IMAP's
COMPRESS DEFLATE I/O traffic (e.g. from rawlog).
- IMAP: Fixed LIST-STATUS when listing subscriptions with
subscriptions=no namespaces.
- IMAP: Fixed SELECT QRESYNC not to crash on mailbox close if a lot of
changes were being sent.
- quota: Don't count virtual mailboxes in quota
- doveadm expunge didn't always actually do the physical expunging
- Fixed some index reading optimizations introduced by v2.0.5.
- LMTP proxying fixes
v2.0.6 2010-10-21 Timo Sirainen <tss@iki.fi>
* Pre-login CAPABILITY includes IDLE again. Mainly to make Blackberry
servers happy.
* auth: auth_cache_negative_ttl default was 0 in earlier v2.0.x, but it
was supposed to be 1 hour as in v1.x. Changed it back to 1h.
If you want it disabled, make sure doveconf shows it as 0.
+ dbox: Added support for saving mail attachments to external files,
with also support for single instance storage. This feature hasn't
had much testing yet, so be careful with it.
+ doveadm: Added import command for importing mails from other storages.
+ Reduced NFS I/O operations for index file accesses
+ dbox, Maildir: When copying messages, copy also already cached fields
from dovecot.index.cache
+ mdbox: Added mdbox_preallocate_space setting (Linux+ext4/XFS only)
- Maildir: LDA/LMTP assert-crashed sometimes when saving a mail.
- Fixed leaking fds when writing to dovecot.mailbox.log.
- Fixed rare dovecot.index.cache corruption
- IMAP: SEARCH YOUNGER/OLDER wasn't working correctly
v2.0.5 2010-10-01 Timo Sirainen <tss@iki.fi>
* acl: Fixed the logic of merging multiple ACL entries. Now it works as
documented, while previously it could have done slightly different
things depending on the order of the entries.
* virtual: Allow opening virtual mailboxes that refer to non-existing
mailboxes. It seems that the benefits of this outweigh the lack of
error message when typoing a mailbox name.
+ Added some disk I/O optimizations to Maildir and index code. They're
especially helpful with short-lived connections like POP3.
+ pop3: Added pop3_fast_size_lookups setting.
- doveconf sometimes failed with complaining about missing ssl_key
setting, causing e.g. dovecot-lda to fail.
- lda: If there's an error in configuration, doveconf didn't exit with
EX_TEMPFAIL as it should have.
- sdbox: Fixed memory leak when copying messages with hard links.
- zlib + sdbox combination didn't work
- zlib: Fixed several crashes, which mainly showed up with mbox.
- quota: Don't crash if user has quota disabled, but plugin loaded.
- doveadm fetch uid was actually returning sequence, not uid.
- v2.0.4's subscription listing ignored (and logged a warning about)
subscriptions=no namespaces' entries in some configurations.
(So listing shared mailboxes' subscriptions could have been broken.)
- acl: Fixed crashing when sometimes listing shared mailboxes via
dict proxy.
v2.0.4 2010-09-26 Timo Sirainen <tss@iki.fi>
* multi-dbox: If :INDEX=path is specified, keep
storage/dovecot.map.index* files also in the index path rather than
in the main storage directory.
WARNING: if you specified :INDEX= with earlier mdbox installation,
you must now manually move the storage indexes to the expected
directory! Otherwise Dovecot won't see them and will rebuild the
indexes, possibly unexpunging some mails.
- Maildir: Copying messages with hard links sometimes caused the
source maildir's entire tmp/ directory to be renamed to destination
maildir as if it were a message.
- Maildir: v2.0.3 broke expunging copied messages sometimes
- Maildir: INBOX whose tmp/ directory was lost couldn't be opened
- single-dbox: Messages weren't copied with hard links
- vpopmail support is hopefully working again.
- dsync: POP3 UIDLs weren't copied with Maildir
- dict file: Fixed fd leak (showed up easily with LMTP + quota)
v2.0.3 2010-09-17 Timo Sirainen <tss@iki.fi>
* dovecot-lda: Removed use of non-standard Envelope-To: header as a
default for -a. Set lda_original_recipient_header=Envelope-To to
returns the old behavior.
+ Added support for reverse quota warnings (i.e. when quota goes back
under the limit). This is enabled by adding '-' to beginning of
quota_warning value. Based on patch by Jeroen Koekkoek.
+ dovecot-lda: Added lda_original_recipient_header setting, which is
used for getting original recipient if -a isn't used.
+ dovecot-lda: Added -r parameter to specify final recipient address.
(It may differ from original address for e.g. aliases.)
+ Maildir: uidlist file can now override message's GUID, making it
possible for multiple messages in a mailbox to have the same GUID.
This also fixes dsync's message conflict resolution.
- dovecot-lda: If destination user isn't found, exit with EX_NOUSER,
not EX_TEMPFAIL.
- dsync: Fixed handling \Noselect mailboxes
- Fixed an infinite loop introduced by v2.0.2's message parser changes.
- Fixed a crash introduced by v2.0.2's istream-crlf changes.
v2.0.2 2010-09-08 Timo Sirainen <tss@iki.fi>
* vpopmail support is disabled for now, since it's broken. You can use
it via checkpassword support or its sql/ldap database directly.
- maildir: Fixed "duplicate uidlist entry" errors that happened at
least with LMTP when mail was delivered to multiple recipients
- Deleting ACLs didn't cause entries to be removed from acl_shared_dict
- mail_max_lock_timeout setting wasn't working with all locks
- auth_cache_size setting's old-style value wasn't autoconverted
and it usually also caused a crash
v2.0.1 2010-08-24 Timo Sirainen <tss@iki.fi>
* When dsync is started as root, remote dsync command is now also
executed as root instead of with dropped privileges.
- IMAP: QRESYNC parameters for SELECT weren't handled correctly.
- UTF-8 string validity checking wasn't done correctly (e.g.
mailbox names in Sieve fileinto)
- dsync: Fixed a random assert-crash with remote dsyncing
v2.0.0 2010-08-16 Timo Sirainen <tss@iki.fi>
* Dovecot uses two system users for internal purposes now by default:
dovenull and dovecot. You need to create the dovenull user or change
default_login_user setting.
* Global ACLs are now looked up using namespace prefixes. For example
if you previously had INBOX. namespace prefix and a global ACL for
"INBOX.Sent", it's now looked up from "INBOX.Sent" file instead of
"Sent" as before.
* Maildir: File permissions are no longer based on dovecot-shared file,
but the mailbox directory.
+ Redesigned master process. It's now more modular and there is less
code running as root.
+ Configuration supports now per-local/remote ip/network settings.
+ dsync utility does a two-way mailbox synchronization.
+ LMTP server and proxying.
+ Added mdbox (multi-dbox) mail storage backend.
+ doveadm utility can be used to do all kinds of administration
functions. Old dovecotpw and *view utilities now exist in its
subcommands.
+ imap and pop3 processes can now handle multiple connections.
+ IMAP: COMPRESS=DEFLATE is supported by imap_zlib plugin
+ director service helps NFS installations to redirect users always
to same server to avoid corruption
v2.0.rc6 2010-08-13 Timo Sirainen <tss@iki.fi>
- dict quota didn't always decrease quota when messages were expunged
- Shared INBOX wasn't always listed with FS layout
v2.0.rc5 2010-08-09 Timo Sirainen <tss@iki.fi>
- Using more than 2 plugins could have caused broken behavior
(more fixes for this)
- Listescape plugin fixes
- mbox: Fixed a couple of assert-crashes
- mdbox: Fixed potential assert-crash when saving multiple messages
in one transaction.
v2.0.rc4 2010-08-04 Timo Sirainen <tss@iki.fi>
+ director: Added director_doveadm_port for accepting doveadm
TCP connections.
+ doveadm: Added client/server architecture support for running mail
commands. Enable this by setting doveadm_worker_count to non-zero.
+ mail-log: Added support for mailbox_create event.
+ imap_capability = +XFOO BAR can be used to add capabilities instead
of replacing the whole capability string.
+ virtual storage: Added support for IDLE notifications.
- doveadm mailbox status: Fixed listing non-ASCII mailbox names.
- doveadm fetch: Fixed output when fetching message header or body
- doveadm director map/add/remove: Fixed handling IP address as
parameter.
- dsync: A few more fixes
v2.0.rc3 2010-07-20 Timo Sirainen <tss@iki.fi>
* Single-dbox is now called "sdbox" instead of "dbox".
"dbox" will stay as an alias for it for now.
+ Added mail_temp_dir setting, used by deliver and lmtp for creating
temporary mail files. Default is /tmp.
+ doveadm: Added "director map" command to list user -> host mappings.
- imap: Fixed checking if list=children namespace has children.
- director: If all login processes died, director stopped reading
proxy-notify input and caused future login processes to hang
- mail_log plugin configuration was broken
- Using more than 2 plugins could have caused broken behavior
- mdbox: Race condition fixes related to copying and purging
- dsync: Lots of fixes
v2.0.rc2 2010-07-09 Timo Sirainen <tss@iki.fi>
- Fixed a crash with empty mail_plugins
- Fixed sharing INBOX to other users
- mdbox: Rebuilding storage was broken in rc1
