Perl warnings for each mail (XX or run?) are redirected to a newly created mail in the target Maildir's inbox, as well as printed to stderr.
Log writes to stderr only.
bin/init-mailmover redirects mailmover's stdout and stderr to a
daemontools multilog dir, which will contain the Log messages from
above.
To run the test suite of the functional-perl submodule (although the kind of test most likely to fail is rather unlikely to be relevant for better-qmail-remote):
cd functional-perl
./test.pl
To run the t/local_corpus test, you need to put maildirs holding a set of to-be filtered mails (in MaildirIn) and how you want it to be filtered (in Maildir), both committed to Git repositories within those folders. An unclean working dir status after conversion represents a test failure.
To run the tests:
./test.pl
