Hi, 

 

Hoping somebody can help with a problem.  For some time now, many of our
customers have been complaining that email that originates from our mail
exchange (local relays) is not being delivered to their customers. I
have checked rdns, blacklists, etc. I really am not sure why, but I am
trying some experiments. One potential issue I have noticed is spam
checking headers for locally relayed emails. 

 

I have all my local networks specified by the line:

trusted_networks 192.168.1.0/24 10.184.0.0/24

 

This certainly adds the ALL_TRUSTED test to my headers for emails that
come from servers that those ip ranges. However, I suspect that perhaps,
part of the issue with these emails not getting through (yahoo and
hotmail rejected some of my test emails, but gmail let them through) is
that the message already has X-SPAM headers with a positive score
(although under the 5.0 threshold.) I was hoping to completely bypass
spamassassin for mail originating in the local ip range or at least
strip those emails of any spam checking headers. Any ideas how to
accomplish this?

 

The mail server is running Debian with Sendmail, spamassassin milter,
and spamassassin configured site-wide. The milter is accessed via
sendmail.mc line:

INPUT_MAIL_FILTER(`spamassassin',`S=local:/var/run/sendmail/spamass.sock
, F=,T=S:4m;R:4m;E:10m')dnl

 

Thanks, I really appreciate you reading this.
