Sorry a bit late to the party on this one, but a couple *very* simple
things I do to keep HTML/any formatting email off my lists is adding a
couple lines "Hold posts with header value matching a specified regexp"
textarea box on the 'Privary Options' section of your list administration
those lines catch 98% of formatted messages and attachments from going to
the list. as the 'standard' rejection message on the admindb page, i have
something like, "Please do not post HTML/RTF formatted emails or
include attachments with your post. Please read thelist info and
guidelines available at http://foo.org/listinfo.html" and the 'reject with
the explanation below' radio button checked by default.
of course, there are better ways to do it which have been mentioned on
again, this is a *very* simple way to go about it and is adequate for
small - medium sized lists. ideally, it gets stripped automagically.
