After a close inspection of the headers, I can see that all the email received have headers injected by spamassassin and this revealing line: "Received: by email.example.com (Postfix, from userid 115)" User 115 is "debian-spamd". So I'm guessing I must have configured SA poorly. I probably know even less about SA than postfix. :) Thanks for your help! -- Prometheus Labor Communications, Inc. http://prometheuslabor.com 413-572-1300 UnionConnect Phone App for Labor Unions http://unionconnect.com
