hypothetical... spam tagging by spamassassin is "expensive" by design so it should be the last step in a long chain of different "antispam" features mostly i.e postscreen, clamav-milter, greylisting, rbl filtering, spf dkim dmarc checks Speculation... big spam mails sourced by hacked big mail providers accounts are perhaps most difficult to catch ( cause they pass spf dkim etc checks before ) So an idea might be switch those providers in another scan chain as other mails by milter-manager conditions, you might use multiple instances of spamass-milter and/or spamassassin with different setups. Multiple other "switches" may integrated with other milters features For sure such stuff has to be checked against real world examples an log analysis. At the end this should give most flexible chances to goal multiple scenarios.
