Spamassassin is a tool to determine the spamminess of a message, not
to check whether attachments to that message pose security risks.

Fine. Your site email policy, then, is "no emails with executable
attachments will be accepted". This is the default policy of the
sanitizer. Take a look at the link.

That's a very heavyweight solution to "I don't want any .exes at all".

I follow the UNIX philosophy: write a small tool that does one job and
does it extremely well, and chain it with other similar tools. Adding
antivirus and other security-related processing to SA dilutes its
effectiveness and distracts the developers from making it the best
anti-bulk-unsolicited-email tool around.

I'd rather have SA be the best antispam tool available anywhere than a
swiss army knife that does many things and none of them well.
