RE: [cobalt-users] mail server not responding update:



Just a thought.  I had the very same problem.  The SMTP server would not
respond temporarily due to heavy load.  The reason for the heavy load as it
turned out was that someone was using a FormMail.pl exploit to send spam
through our machine on a hosted customer's site.  Thousands of emails per
day! Totally anonymous spamming. It had me baffled for a while.  Look and
see if you have the FormMail.pl or FormMail.cgi script on your machine
anywhere and what version it is.

I did some scouting in the mailog - here are the entries that I thought were of interest. Any able to tell me anything about what I am looking at (other than the obvious, it isn't working :)

The sitescope entry at the bottom is the program our host company uses to monitor if our servers are alive ... it has been telling me that my SMTP server is down periodically; although it is really obvious when I can't send any mail.

Anyone suspect a hard drive? I have no reason to necessarily think that.

THANKS!!!!!!
Jale, where I'll be if I don't solve this soon.
