You must be using the Outlook addin, yes?  Any other way of using the
SpamBayes codebase does know the names of attachments, and does pick apart
all MIME attachments with type text/*.  The Outlook addin does neither,
because Outlook destroys the original MIME structure of incoming email, and
so our project's MIME parser has nothing left to work with.

This won't change until someone contributes code to do a better job of
trying to guess (and recreate) the original MIME structure, from all the
places Outlook scattered the pieces.

That said, I get lots of these kinds of virus bounces too, and after patient
training they never show up in my Outlook Inbox anymore.  I get a few new
ones in Unsure each day now, but usually in a language I don't recognize
