my postfix instance config currently includes my list of milters -o smtpd_milters=unix:/run/opendkim/opendkim.sock,unix:/run/opendmarc/opendmarc.sock,unix:/run/milter-regex/milter-regex.sock,unix:/run/clamav/clamav-milter.sock,unix:/run/spamass-milter/spamass-milter.sock
for a rejection by any given milter, i see in cleanup log Jun 11 04:33:18 mx postfix/cleanup[18542]: 49jV46213qzy59: milter-reject: END-OF-MESSAGE from localhost[127.0.0.1]: 5.7.1 Service unavailable; from=<i...@deltareclame.nl> to=<m...@example.com> proto=ESMTP helo=<cloud3.deltareclame.nl> can postfix logging itself identify the specific milter that fails/rejects? e.g., in this^ case, it's unix:/run/spamass-milter/spamass-milter.sock i can configure reject messages in (some) milters to provide identifying detail, but that reply gets passed on to external connection. any way to log that detail only _privately_?
