Mailscanner/Sendmail Relaying has stopped!!

[Derek Winkler]

This happened to me when the internal systems weren't available for a long
period of time.
 
Was using mailertable to route to internal systems.
 
Was fixed after restarting named.

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.



Feb 19 04:23:15 gateway sendmail[23338]: k1JCN1uL020946:
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



Feb 21 14:20:06 gateway sendmail[11683]: k1LMHrqI011613:
to=<stork at mydomain.ca>, delay=00:02:12, xdelay=00:02:00, mailer=esmtp,
pri=177260, relay=smtp. mydomain.ca [207.216.243.61], dsn=4.0.0,
stat=Deferred: Connection timed out with smtp.mydomain.ca.


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