[Mailman-Users] blocking MIME

[Phillip Lord]

       Hello all

       I'd like to block all MIME messages going to a mailman
mailing list, or alternatively hold them up for moderation. This is
partly so that I can block HTML mail because its annoying, and pretty
much everything else to avoid the mail virus problem. 

       Is there a simple way that I can achieve this from within 
mailman. Currently the only option I can think of is prefiltering
mail, and killing all mime. 

        Cheers

        Phil
