Postfix / Dovecot / ClamAV / Spamassassin
2016-12-12 A whole buncha' links with contradictory information on how to properly set up a mail server ;-)
Disclaimer - My primary goal is to add proper Spamassassin (SA) filtering to an existing Postfix / Dovecot / roundcube installation, i.e.:
- use SA as a milter (mail filter) to attribute a spam score to incoming mail
- keep SA up-to-date
- train SA with spam/ham from the users' virtual mailboxes
- train SA according to user decisions (actual user or trained mail client with automatic/trained spam detection)
Here we go!
