Depends on your list software. On my LISTSERV lists, I use the
"sizelim" header item (set to 150 lines, which seems to work without
being TOO restrictive).

On my Lyris lists, I am right now in the process of developing the
necessary filter texts to efficiently block ALL attachments,
regardless of the number of lines in the message. (Lyris permits
you to filter on "action phrases," which can trigger specific
actions -- such as rejecting the attempted post and returning a
custom message that says, "You idiot, we TOLD you that you weren't
supposed to post attachments to the list.")

I've never figured a way to do wither of these in ListProc. Majordomo
has the capability, but requires doing some PERL coding. <yuck>
