It is amazing how many vacation implementation are written by the
(hopefully terminally) clueless.

Unless the vacation program quotes back the message it is reponding
to, it is difficult for Mailman to distinguish between a vacation
loop and am active poster.  That said, implementing something like
Formail's MsgID cache for Mailman, except instead of cacheing
MessageIDs cacheing MD5's of message bodies might be a good idea...
