sendmail
is timing out on one of our CentOS servers. Here is my test
[root@testserver ~]# echo "Subject: test" | /usr/lib/sendmail -v [email protected]
Here is the output:
[email protected]... Connecting to [127.0.0.1] via relay...
220 testserver.ourdomain.com ESMTP Sendmail 8.13.8/8.13.8; Thu, 23 Jun 2011 14:32:18 -0600

And then a minute later, /var/log/maillog
shows the following:

In that second log entry, it appears to be trying to use our external company website to try to relay the email... I have no idea why its trying to do that. Another it guy setup this server recently so I'm not sure if he changed the sendmail configuration or what. Where should I be looking to remedy this?
(obviously names, domain names and IP addresses have been changed in the above logs to protect the innocent)
