I am trying to reconfigure my postfix server to get rid of false
positives in the masschecks.
* I run my own postfix server at example.com.
* Several of my users have IMAP accounts on my server. They send their
outgoing mail via my server with SMTP-after-IMAP. This has been working
fine except this causes trouble for the masschecks in cases where they
sent mail to other users on my server. Their legitimate mail is
triggering rules like RCVD_IN_SORBS_DUL, RDNS_DYNAMIC, and occasionally
RCVD_IN_PBL because the only Received header is the delivery directly
from their home IP address.
* I enabled TLS with SASL authentication. This is working, but the
following Received header is still triggering these rules.
Received: from [XX.XX.XX.XX] (XX-XX-XX-XX.isp.example.com
[XX.XX.XX.XX]) (using SSLv3 with cipher DHE-RSA-AES256-SHA (256/256
bits)) (No client certificate requested) by mail.example.com (Postfix)
with ESMTP id DEADBEEF47 for <u...@example.com>; Sun, 11 Oct 2009
02:01:37 -0400 (EDT)
...
No, score=0.6 required=5.0 tests=BAYES_00,RCVD_IN_SORBS_DUL,
RDNS_DYNAMIC,TVD_SPACE_RATIO autolearn=no version=3.3.0-alpha3-r816412
Is it possible to configure postfix to write some kind of auth message
in the Received line if you had authenticated?
Does spamassassin and masscheck have any way to recognize such headers
to know to skip that line for rule checks?
