I've been using most of these on several lists. However, I've been having
trouble writing a Regular Expression that would catch any uuencoded file in the
body of a message. I wrote something to catch WINMAIL.DAT (something stuck in
by an old Microsoft application; I have no idea what it was). But I've been
told that there's a general format or identification for uuencoded files that
should be trappable.

Any thoughts?

We asked folks to turn off vcards as attachments are generally banned.
