We have a need for a relatively painless anti-spam solution that
would reduce the amount of incoming spam (via postfix mail router).
The problem is that i have little knowledge on what this actually
means. Googling reveals a whole "universe" of interesting ways but
what should i pursue?
The things that are important to me is:
* Once it is setup then it would require no additional maintenance.
* Potential spam messages are marked with a special header that can
be filtered on user discretion on their local mail client software.
Install the following:
/usr/ports/mail/postfix-policyd-weight
/usr/ports/mail/postgrey
/usr/ports/mail/p5-Mail-SpamAssassin
/usr/ports/security/amavisd-new
/usr/ports/security/clamav
policyd + postgrey provide rather good, very lightweight initial
filtering of email without taking up a lot of memory or resources, and
remove a lot of workload, so that the Amavisd+ClamAV+SA combination
only has to do virus-scanning and SpamAssassin's expensive Bayesian
word-mangling on emails which seem to be legit.
