I see no documents in the Dovecot documents wiki on how Dovecot features can be used in the fight against spam. One hit came up in a search, and it was about how to fight spam in the MoinMoin Wiki itself (e.g. TextCHAs and such).
- Set up postfix (or whatever MTA you are using) to reject as much as possible at SMTP time.
If done right postfix can reject 90+% (depending on how much /what type of spam your domains get) with pretty much zero FPs...
Lots of examples down in the UCE/Virus section here:

- Add amavisd-new+spamassassin to the mix, and tag+deliver anything it detects as spam into the junk folder using sieve...

There is also a plugin for dovecot that makes it easy for users to reclassify stuff as spam or not spam by simply moving the messages to the appropriate folder, but I think it is mainly designed for DSPAM... anyone using it with spamassassin?
