I think I found the root cause of the problem (other than me being a
clueless idiot). I had this in my master.cf:
smtp inet n - y - - smtpd
-o content_filter=spamassassin
submission inet n - y - - smtpe
-o content_filter=spamassassin
-o syslog_name=postfix/submission
-o smtpd_tls_security_level=may
-o smtpd_sasl_auth_enable=yes
Removing the second SA content filter in the "submission" stanza did
the trick. I was wondering why outgoing mail was getting fed through
SA. It's not supposed to be, is it?
