I'm using procmail too, in my machine to move mails marked as spam.
But the problem I have, is that all the users of the server want a kind of
spam filter in Roundcube, because they want to redirect the spam marked
mails to another folder than inbox, and they are simple users so they can't use procmail. May be exists some implementation of filters in
roundcube? :D I'm using postfix+spamassassin+amavis-new. Do you know some scheme
to solve this problem?
Use DSPAM, it is more accurate than SpamAssassin for us. The DSPAM
binary replaces procmail as the MDA, and it can be configured to move
messages marked as spam to a separate user directory rather than a
quarantine.
Pros:
Each user trains the filter as they desire, so one user's opinion of
what is spam doesn't conflict with another user's opinion.
No rules to update
Very accurate, keeps up with changes in spam techniques
Cons:
Processor and database intensive, you may need bigger hardware to
handle it.
User's are lazy and don't want to train the filter
The filter needs a baseline of 1500 messages to start making good
decisions
IMHO, the MUA isn't the place for filtering. We also use greylisting before the message gets to DSPAM.
