Mailscanner/Sendmail Relaying has stopped!!

[Rob Poe]

Someone change your /etc/mail/local-host-names, /etc/mail/relay-domains or /etc/mail/mailertable ??

Well I dont know what happened today but here is my setup.

gateway machine (running MailScanner on RHES4) which accepts all mail for the domain mydomain.ca

This
machine is out on the DMZ and so sendmail has a routing table entry to
send all mail for our domain, back into an internal Scalix Mail server.
Below is a "normal" maillog entry when it was working. You can see the
mail getting relayed correctly to the internal mail server,
penguin.mydomain.ca.

to=<stork at mydomain.ca>, delay=00:00:13, xdelay=00:00:00,
mailer=esmtp, pri=177672, relay=penguin.mydomain.ca. [192.168.1.3], dsn=2.0.0, stat=Sent (Ok)


But
now, for some reason, MailScanner/Sendmail is not relaying the mail it
receives, back into the primary mail server, penguin.mydomain.ca?
Instead it is trying to send it back out to itself basically

All my mail is piling up in the sendmail que. Any suggestions??? I am in panic mode_______________________________
