Actually what you are describing as a 'third Received header' is a
/first/ Received header traceline of the *original* item, which your
provider's server calls

Content-Description: original message before SpamAssassin

of the mime structure of the attachment.  That's what I was describing
in news:[email protected]

You are saying that all of 'these' spams have attachment headers which
show the source IP just like the example item which is actually a viral
propagation, not a 'simple' or regular spam per se.

Then all you will have to do is find a technique to isolate those
original 'attachment' headers, which are also contiguous with the
spambody [see body2 above],  to submit to the parser.  In such
isolation, the parser can not only find the source IP but also any
contained spamvertiser URLs.
