Installs and configures postfix for client or outbound relayhost, or to do SASL authentication.
On RHEL-family systems, sendmail will be replaced with postfix.

The main.cf template has been simplified to include any attributes in the node['postfix']['main']
data structure. The following attributes are still included with this cookbook to maintain some semblance of backwards compatibility.
This change in namespace to node['postfix']['main']
should allow for greater flexibility, given the large number of configuration variables for the postfix daemon. All of these cookbook attributes correspond to the option of the same name in /etc/postfix/main.cf
.

Installs the postfix package and manages the service and the main configuration files (/etc/postfix/main.cf
and /etc/postfix/master.cf
). See Usage and Examples to see how to affect behavior of this recipe through configuration.
For a more dynamic approach to discovery for the relayhost, see the client
and server
recipes below.
Use this recipe to have nodes automatically search for the mail relay based which node has the node['postfix']['relayhost_role']
role. Sets the node['postfix']['relayhost']
attribute to the first result from the search.
Includes the default recipe to install, configure and start postfix.
Does not work with chef-solo
.
Sets up the system to authenticate with a remote mail relay using SASL authentication.
To use Chef Server search to automatically detect a node that is the relayhost, use this recipe in a role that will be relayhost. By default, the role should be "relayhost" but you can change the attribute node['postfix']['relayhost_role']
to modify this.
Note This recipe will set the node['postfix']['mail_type']
to "master" with an override attribute.
Manage /etc/aliases
with this recipe. Currently only Ubuntu 10.04 platform has a template for the aliases file. Add your aliases template to the templates/default
or to the appropriate platform+version directory per the File Specificity rules for templates. Then specify a hash of aliases for the node['postfix']['aliases']
attribute.
Arrays are supported as alias values, since postfix supports comma separated values per alias, simply specify your alias as an array to use this handy feature.

On systems that should simply send mail directly to a relay, or out to the internet, use recipe[postfix]
and modify the node['postfix']['relayhost']
attribute via a role.
On systems that should be the MX for a domain, set the attributes accordingly and make sure the node['postfix']['mail_type']
attribute is master
. See Examples for information on how to use recipe[postfix::server]
to do this automatically.
If you need to use SASL authentication to send mail through your ISP (such as on a home network), use postfix::sasl_auth
and set the appropriate attributes.
For each of these implementations, see Examples for role usage.
The example roles below only have the relevant postfix usage. You may have other contents depending on what you're configuring on your systems.
The base
role is applied to all nodes in the environment.
name "base"
run_list("recipe[postfix]")
override_attributes(
"mail_type" => "client",
"postfix" => {
"main" => {
"mydomain" => "example.com",
"myorigin" => "example.com",
"relayhost" => "[smtp.example.com]",
"smtp_use_tls" => "no"
}
}
)
The relayhost
role is applied to the nodes that are relayhosts. Often this is 2 systems using a CNAME of smtp.example.com
.
name "relayhost"
run_list("recipe[postfix::server]")
override_attributes(
"postfix" => {
"mail_type" => "master",
"main" => {
"mynetworks" => [ "10.3.3.0/24", "127.0.0.0/8" ],
"inet-interfaces" => "all",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
)
The sasl_relayhost
role is applied to the nodes that are relayhosts and require authenticating with SASL. For example this might be on a household network with an ISP that otherwise blocks direct internet access to SMTP.
name "sasl_relayhost"
run_list("recipe[postfix], recipe[postfix::sasl_auth]")
override_attributes(
"postfix" => {
"mail_type" => "master",
"main" => {
"mynetworks" => "10.3.3.0/24",
"mydomain" => "example.com",
"myorigin" => "example.com",
"relayhost" => "[smtp.comcast.net]:587",
"smtp_sasl_auth_enable" => "yes"
},
"sasl" => {
"smtp_sasl_passwd" => "your_password",
"smtp_sasl_user_name" => "your_username"
}
}
)
For an example of using encrypted data bags to encrypt the SASL password, see the following blog post:
- http://jtimberman.github.com/blog/2011/08/06/encrypted-data-bag-for-postfix-sasl-authentication/
If you'd like to use the more dynamic search based approach for discovery, use the server and client recipes. First, create a relayhost role.
name "relayhost"
run_list("recipe[postfix::server]")
override_attributes(
"postfix" => {
"main" => {
"mynetworks" => "10.3.3.0/24",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
}
)
Then, add the postfix::client
recipe to the run list of your base
role or equivalent role for postfix clients.
name "base"
run_list("recipe[postfix::client]")
override_attributes(
"postfix" => {
"mail_type" => "client",
"main" => {
"mydomain" => "example.com",
"myorigin" => "example.com"
}
}
)
If you wish to use a different role name for the relayhost, then also set the attribute in the base
role. For example, postfix_master
as the role name:
name "postfix_master"
description "a role for postfix master that isn't relayhost"
run_list("recipe[postfix::server]")
override_attributes(
"postfix" => {
"main" => {
"mynetworks" => "10.3.3.0/24",
"mydomain" => "example.com",
"myorigin" => "example.com"
}
}
)
The base role would look something like this:
name "base"
run_list("recipe[postfix::client]")
override_attributes(
"postfix" => {
"relayhost_role" => "postfix_master",
"mail_type" => "client",
"main" => {
"mydomain" => "example.com",
"myorigin" => "example.com"
}
}
)
