If you want to unconditionally do what the subject of this message
says, I think the patch is pretty simple, but I haven't tested it at
all so beware.

In the module Mailman/Handlers/Hold.py you will see

    #
    # Implicit destination?  Note that message originating from the
Usenet
    # side of the world should never be checked for implicit
destination.
    if mlist.require_explicit_destination and \
           not mlist.HasExplicitDest(msg) and \
           not msgdata.get('fromusenet'):
        # then
        hold_for_approval(mlist, msg, msgdata, ImplicitDestination)
        # no return


I think all you need to do is replace

        hold_for_approval(mlist, msg, msgdata, ImplicitDestination)

with

        raise Errors.DiscardMessage

The discard will still be logged in 'vette', but otherwise, the message
will just disappear.
