Alle,
We are running SA V3.2.4 on RHEL5.1. We would like to whitelist mail
coming from inside our network. Spamassassin is located on our DMZ servers.
Users use the internal SMTP relay to send mail. The internal domain is
foo.ac.jp. The external domain is foo.org. (Don't ask). *All* hostnames are
*.foo.ac.jp, both internal and on the DMZ, but the DMZ machines are only
addressable by their foo.org addresses from the outside. There are no rDNS
entries for the internal servers for the DMZ machines to query.
Is there any was of doing this without adding rDNS records in
external DNS?
Your MTA should bypass SA if the message is from the "inside network".
That's how I have it set up here.
As it is, SA just scans what you feed it. Therefore, if there is further
fine tuning as to what gets scanned and what does not is solely made by
your MTA.
