Hello,
An 'mail loop back' error occurs whenever I send mail to myself. Here is
the Mail Delivery report:
The original message was received at Thu, 20 May 2004 10:40:00 -0400 (EDT)

Any ideas as to what the 'local configuration error' could be? Where
should I be looking?
Thanks,

Where > should I be looking?Hello Omar, Supposing you are using the standard FBSD sendmail setup: Check with echo '$=w'|sendmail -bt -d0.1 how sendmail knows about itself domain names. You may then adapt by editing /etc/mail/local-host-names Hope this helps.

Where >should I be looking?This is more application specific, so a sendmail newsgroup or freebsd-questions is perhaps a more appropriate place to ask this question. sendmail is VERY good for logging verbosity. Always look through /var/log/maillog. If there is nothing there, increase the LogLevel. Also, examine the mail headers of a test message to see where its going back and forth. Without seeing details like /etc/mail/access /etc/mail/mail/local-host-name or /etc/mail/mailertable or /etc/mail/virtusertable, my guess is that you forgot to add the target domain into /etc/mail/access and /etc/mail/mail/local-host-name (assuming Fw points to /etc/mail/local-host-names) ---Mike

I just ran across this when I moved a machine from one net to another. Check your ip address settings for your host.
