I'm trying to put together a system to block attachments.
The idea is to point the existing MX records to a new system running
sendmail/procmail and perhaps a few perl scripts.
My pseudocode goes something like this:
If the message's from line shows that it comes from somename.com, then pass it
on to mailhost2 unchanged.
Else if the message contains any attachments, stash it in a local file,
Else pass it on to mailhost 1 or mailhost2 depending on the MX information.
(end pseudocode)
Is procmail capable of filtering messages that are *on the way to somewhere
non-local*? If so, how?
Thanks, [RC]
