Hi,

I am working to implement TMDA with a mailing list server, in this case
Mailman. We have the following kind of setup for e-mail aimed at a
mailing list: SpamAssassin -> TMDA -> Mailman -> local/external
delivery. We use Exim.

SpamAssassin tags spam as such, and TMDA, for the mailinglists, will ask
confirmation for any message tagged as Spam. This works just fine.

The problem we're having occurs with the local delivery, during which we
also want to give users the opportunity to run their e-mail through
TMDA, and thus have extra rules/whitelists/blacklists. We have a working
setup for this too, but when local subcribers' rules are more strict
than the global rules, and ask for a confirmation, potentially there
will be a lot of confirmation requests sent to the list owner (or, in
the case of expansion of an alias file, to the sender of the message).
We don't want that.

Ideally, TMDA would send out 1 confirmation request for the message
(preferably with a from address that is not based on the requesting
user's, but on the list/alias address) as soon as one of the members
asks for it. TMDA would then continue to deliver the message as normal
to all members of the list that don't require confirmation, and freeze
the message for the ones that do. If a confirmation comes in, TMDA would
deliver the mail to the remaining members.

I guess you could call this 'hierarchical confirmation of messages',
where a confirmation for one listmember would approve the message
automatically for anyone receiving the message, systemwide.

I guess what we want is a mailing list aware of TMDA. Is there a way to
do this with TMDA as it exists now? If not, does anyone have ideas on
how to go about this?

Bye for now,
Ward.
