What was in the "To:" header?  What about the envelope sender?  Note 
that this is usually recorded as the "Return-path:" header, or in 
what is sometimes referred to as the "From_" header.

No, it seemed to recognize what the message-id header was, but there 
was something else it didn't recognize.  That's what we need to 
figure out.

I helped build the original versions of those machines at AOL, so I'm 
pretty sure I know what they're doing.

We'd have to look more deeply at all of the headers that were 
actually present, and then we'd have to look through the code paths 
to see what might have resulted in that message.  Without the that 
information, we'd just be taking shots in the dark.
