(O.T.) Exchange 2003 SMTP?

Dan,
I recently saw this at one of my clients.
If your exchange server is behind a nat firewall (like a linksys router) and
the one wan ip address for the lan is the same as the exchange server, you
could be listed by a service describing you as infected. This is not exactly
the same as a traditional open relay, but you mioght be "blacklisted" and
therefore outbound recipients may be rejecting your mail.
Check this out:

Enter your address and see if it is listed. If so, you will have to submit a
request to be removed. However, you want to make sure as soon as possible
that the infected machine is removed so you are not listed again.

Sorry for the off topic post, but I am a little concerned about this one

I was recently notified by user that outbound e-mail was not being
delivered to outside recipients. Looking at my Exchange 2003 Queues I
see 4 SMTP connector lines with strange entries SMTP connector
glezdejee.shankscape.com (smtp connector). Are these normal entries, or
is my server acting as a relay? I recently heard of a new e-mail virus
using SMTP could this be a possibility? My understanding of Exchange is
rather limited any help would be greatly appreciated.

Thanks
