<p>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.</p>
<p>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.<br>

<p>Hello,</p>
<p>For MTA server, I use Postfix, with some blacklists (DNSBL).<br>
</p>
<p>For filtering then: SpamAssassin + Clamav works well.<br>
