Yes I think so - if I read your message right. The mail message will be MIME
encoded with this type of header embedded into it:
--Boundary-=_nWlrBbmQBhCDarzOwKkYHIDdqSCD
Content-Type: text/plain
Content-Transfer-Encoding: 8bit
The initial headers must specify what the 'boundary' is by using:
Content-Type: Multipart/Mixed;
boundary="Boundary-=_nWlrBbmQBhCDarzOwKkYHIDdqSCD"
So by filtering the mail looking for something like 'boundary=' should
filter out mail with attachments. You will need to be careful with the
expression you use in the test since you don't want to filter plain text
mail that simply contains 'boundary=' somewhere and secondly there may be
clients that use different wording (the MIME RFC's should probably specify
what is allowed).
