Yes!  That's exactly it.  Right now all I can do is "hold" mails that match
certain headers.  I like that option for certain cases, but I'd like another
(independent) option to completely discard mails that match certain headers.
And while we're at it, why only hold or discard?  Why not offer the same
sets of options available in other places: hold, discard, forward to
someone, etc.

I don't understand something in your mail, however.  You say "you could
either add..." and such, implying that _I_ could do it myself?  Do you mean
that there is a facility for this already in mailman?  Or did you mean that
I could always hack the source and add the feature I wanted?  If you meant
the latter, then I'd prefer if someone more experienced in Python and
Mailman's code do it (what'll take me many hours, Barry can probably do in
his sleep, with _both_ hands tied behind his back. :-)
