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.
