Along those lines, what I'm thinking about is scanning based on mime
rather than size. If the email is plain text or html, then scan no
matter what size it is. If the email has a doc,jpg,pdf or other such
desirable attachment, then scan beneath a size threshold -- or
preferrably up to the attachment envelope. How doable is this with
Spamassassin? I am using Exim 4.50 with content scanning. So checking
for MIME is easy. But scanning up to the attachment envelope is the hard
part.
