Maybe in this case you were being sharked, but before we got everything
clamped down on our servers we saw a number of spammers who were
'multi-hopping' their UCE and including faking headers and sending false
HELO data.

The excerpt below from my archives shows them bouncing mail off our
server, to iea.com, and then to AOL.  The real originator was at rmii.com,
but they attempted to put in some semi-fake headers before that. 

I guess the moral of the story is "trust no one, and filter, filter,
filter..."  Sad, but true.
