[Mimedefang] Sendmail/mimedefang set up problems

[Douglas, Jason]

Hello,

I am installing mimdefang/sendmail on a Mandrake 10.0 Official machine.
I built sendmail from source as per the instructions here:
http://www.rudolphtire.com/mimedefang-howto/#s3 

I also followed the instructions for installing mimedefang, etc. However
I am having a problem with the relaying configuration. Here is basically
the situation:

The box (190.10.9.9, called "spammail") will simply take mail from the
outside world for municipality.clarington.on.ca.
It should scan for spam/viruses...
Then relay to our Exchange server (190.10.9.1, called "moc-exch")

I have been trying to get it to do so by changing local domains, relay
domains, domain masquerading in sendmail but I can't seem to get it to
work. I believe it is tempfailing messages because when I start
forwarding port 25 (at the router) to the spammail box, mail never
reaches the mail logs. Then when I forward port 25 back to the Exchange
server the messages are delivered a short time later (~ 10 mins?). It is
not simply delay between servers, I did some tests and mail is normally
delivered within seconds.

Any help for this type of one-way delivery set up would be greatly
appreciated. I will be happy to provide any config files that you need
to see to help troubleshoot. Thanks.
