Now that I've finally got my Postfix system working, I would like to know
what restrictions I can use to block Spam, Malware and do some content
filtering. Also is there an order that these have to be applied?





Regards



Jon

the first stage is to use smtpd restrictions. In particular,
zen.spamhaus.org. you should reject most of the junk at this level.

after that, pass mail to a content filter. a common choice here is to
use amavisd-new with clamav and spamassassin.

Hey,

* We use maia mailguard and depending upon how you train the bayes it is pretty effective

* It has pretty features where you can quarantine and rescue mails too
