I self host my email since 20+ years. Always done with the postfix + dovecot stack with the works (dkim dmark DNS stuff etc).

In the last few years I just removed all spam filters as they where a chore and didn’t provide no much benefit (3-5 spam emails per week) even if my main email address has been out and about for at least 2 decades or more.

Recently, last few weeks, spam is picking up to the point I receive some 10+ spam emails per day and this is pretty annoying, obviously.

So, what are you doing for spam filtering at server level nowadays? Is it still spamassassin circus? Anything better or more efficient?
