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.
I've started using rspamd in place of SpamAssassin and have been having good results. Built in greylisting, support for spamassassin rules, nice statistics web based GUI.
Only downside is that it can be quirky during the initial setup. It depends on redis for its key lookup backend. Not a big fan of redis, but it works, especially if you have to support multiple rspamd instances on different mail servers, and want to have one main backend to store all the spam/ham hashes in.
