Anybody patching Sendmail to filter _attachments_?

[Bill Woodcock <woody () zocalo net>]

...as opposed to just by subject line?  We're getting a lot of requests
from customers that we MX for to just throw away either all attachments or
any .vbs visual basic attachments.  Obviously the Sendmail-Inc.-approved
fix is subject-line based, which doesn't take care of that.

Anybody else working on this already?
