Here is the /var/log/mail entry from the email that leaked past Amavis-new:

Looks to me like it is getting a '-300' score from some rule that I can't find. The email comes in forged to look as if I had sent it, from '[EMAIL PROTECTED]'. That email address is *not*
in the whitelist in /etc/mail/spamassassin/local.cf

When I run the leaking email message through spamassassin manually, it comes up with a score
of 58.4, quite different from what amavis-new reported above!

I've attached the output of spamassasin on running the leaking email as a gzip file.
Hopefully, that will pass through the email.

Thank you,
Chris Shaker


I've still got the mystery of how his email gets in without being scored by Amavis.
When I run spamassassin on it, it gets a very high score.

Other spam gets filtered just fine. Somehow, this one spammer avoids it.
