<font size="2">I don't know if you've resolved this problem by now Gerald. But "Service unavailable" typically means the server isn't running. So either Sendmail is not running/accepting e-mail messages (most likely), or its not tied to that loopback port (unlikely), or your firewall rules are blocking that port (again unlikely).
<br />
<br />To test, try the command "service sendmail start". If you get a OK back (no error), try that test message again. If the test message works - your server was dead for some reason. Check to see if there is an entry in /etc/rc.d/rc3.d that starts the Sendmail server (S80sendmail).
<br />
<br />If it doesn't work, check your firewall rules with "iptables -L -n". Look to see if there are any rules blocking TCP port 25. And look to see if there is a permit all to 127.0.0.1. There should be one under the "Chain acctin" that looks like " all -- 0.0.0.0/0 127.0.0.1 "
<br />
<br />Last, use "netstat -na" and look for the server listening on the e-mail port. Like this:
<br />"tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN"
<br />
<br />
<br />Good luck. And post back if you need any help.
