Re: Retracing Sender's SMTP IP Address using MS Exchange 5.5

[Steve Sobol <sjsobol () NorthShoreTechnologies net>]

This is off-topic for the NANOG list.

I tend to be pretty good at reading mail headers, so
if you'd like to follow up by sending the headers to
me to take a look at, I can.

Alternatively, you might try SPAM-L. Subscribe,
and post your question with a prefix of "HELP:"  e.g.

Subject: HELP: Please help me track the origin of this message

http://www.claws-and-paws.com/spam-l/ has the FAQ,
with lots of good info including how to subscribe.
