Scanning attachments for spam

Lately a lot of spam has been contained in attachments to otherwise empty 
messages.  Such spam could be easily filtered based on recurring character 
strings if the attachment is scanned.

I have been using procmail to filter spam based on contents of message body 
and I would just like to extend this technique to attachments.

Is there a way how to use procmail for this purpose?  Can you point me to a 
description or an information about such attachments scans?

Thanks
