It's mentioned at the bottom of
but my understanding of the gmail issue is that the gmail poster would
see no messages from any list because they 'match' the sent message.
Other gmail list members would see only one of the list posts because
the ones from other lists all match.

The original 'no dups' patch was intended to do this, but it was never
distributed in an official release. Currently, Mailman delivers from
each list to all regular members of that list except the poster if the
poster selects 'not metoo' and any members in To:, Cc:, Resent-To: or
Resent-Cc: who have selected 'no dups' for that list.
