[cobalt-users] Mailserver keeps crashing

["mail list" <mail.list@xxxxxxxx>]

Hi,

My SMTP server keeps going down.  I've been checking the /var/log/maillog 
file, but I can't make a lot of sense out of what I'm seeing.

Here are a couple lines from the maillog that seem suspicious.  Can anyone 
tell me what these mean and what I should do next?

Mar 26 03:06:33 cobalt2 sendmail[16849]: i2M4A0120430: 
to=1651@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx, ctladdr=kirkkelly (793/100), 
delay=4+03:56:33, xdelay=00:03:09, mailer=esmtp, pri=8400229, 
relay=3219.flyingcoffeebeanmarketing.com. [69.6.57.4], dsn=4.0.0, 
stat=Deferred: Connection timed out with 3219.flyingcoffeebeanmarketing.com.

Thanks,
