/etc/init.d/sendmail stop
omoff -d0 -w smtpd && omon smtpd
/etc/init.d/sendmail start.

You probably have Sendmail or Postfix listening on the External IP on port 25. Sendmail or Postfix should only listen on port 25 on the loopback address 127.0.0.1. Then Scalix SMTP Relay is listening on the external IP on port 25.

I did run the following command:

# strace -f omon "smtp relay" 2> strace &


and the interesting output is this:

Okay, I see the problem.

He removed the spaces on several lines between 'db' and 'files'.

After I put the space back in, the the smtp relay started back up just fine!

Thank you for responding so quickly, and sorry that it wasn't "really" interesting .
