I've used Sendmail + MIMEDefang + SpamAssassin w/clamav for over 15 years. And on the SA side I use all the bells and whistles available like DCC greylisting, all the public blacklists, there are some 3rd party rulesets you can subscribe to, etc.,. In the end its not as good as gmail, but pretty darn close. I block at SA score 4 and above, 4-8 score I dump into a separate quarantine account that I check every now and again for possible errors, and over 8 I drop - no log or bounce. -John On 12/14/18 12:35 PM, Guillaume Tournat wrote:
Hello,
For MTA server, I use Postfix, with some blacklists (DNSBL).
For filtering then: SpamAssassin + Clamav works well.
