And does Postfix connect via the milter and spamc, or does it call spamassassin directly? For example, I have this in /etc/postfix/main.cf:
smtpd_milters = ... unix:spamassassin/spamassassin-milter.sock Another thing to try is enable more logging in spamass-milter to see what it’s doing. What should happen technically is that Postfix connects to the milter, the milter uses spamc to communicate with SpamAssassin/spamd, and finally the milter will add the new headers it receives from SpamAssassin.
