Ugh. Got any bounces from someplace other than AOL? Maybe someplace 
that includes all of the original message?

That's the origin of this bounce. rly-st02.mail.aol.com. It had the 
message but could not deliver it. That's important.

That's odd. I thought that was one of AOL's internal intercept 
machines. They catch connections aimed at outside port 25 from  (most 
of ) their dialup ports and redirect them to the intercept boxes, 
which supposedly do heavy rate-limiting and filtering. My 
understanding was that the rly-x* machines were those intercept 
boxes... That would make this extremely odd.

So basically, rly-st02 tried to pass along the message that it got 
from rly-xf02 to air-xb03, which rejected it. All AOL machines.

This almost looks like it originated inside AOL with someone trying 
to pump it through an external machine but being caught by the 
interceptors, which re-routed it internally and got it bounced. Just 
a guess.

And there we have the mostly-useless snippet from the original 
message. No indication of the actual source. I thought AOL had gained 
a few clues on this and fixed that so all of the real headers 
(including Received headers) were included, but I guess I 
misunderstood... Of course, if this was generated internally to AOL 
(with a fake From address) there might not be any other headers. Hmmm.

IF you have non-AOL bounces, they might be helpful in tracing the 
source and so figuring out if you have a relaying problem or if you 
just have an address that someone forged. If you only have AOL 
bounces, it would tend to support my wild guess as to how the 
original spam might not have ever touched your machine.
