Nope. All you have for each list knows is a bunch of e-mail addresses that are subscribed. When sending out a message that has been cross-posted to multiple lists, one thing you could do is an equivalent to "sort | uniq" for all of the recipient e-mail addresses, but you have no way of know if a single person has multiple different addresses that are subscribed to one or more lists. And I believe that interactive mail messages are handled separately from digests. > Yes, absolutely -- the only key is Message-Id.

There have been many examples of clients that do not create sufficiently unique message-ids for different messages. But if the recipient wants to that that risk within their mail system, that's their choice. > I think, this function is already here.

I guarantee you that this feature does not yet exist in Mailman. > This is true.

Most of the anti-duplication features can't be delivered until Mailman3. The sister-list concept that Mark has introduced with Mailman 2.1.10 is the best we're likely to be able to see for a long time. > AFAIU, the message will appear in the search results multiple times -- once > per mailing list.

Mailman does not incorporate any search function, therefore which searches return which messages is totally and completely irrelevant to Mailman. Moreover, searches across multiple lists should most definitely return multiple hits for the same message, if it was posted to multiple lists. If you want any other kind of behaviour, then that would be up to you and how you configure your particular search query. No search engine author in their right mind should ever consider doing de-duplication on their own, although they might be willing to provide that feature to customers who demand the option. -- Brad Knowles <[EMAIL PROTECTED]> LinkedIn Profile: <http://tinyurl.com/y8kpxu> ------------------------------------------------------ Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://www.python.org/cgi-bin/faqw-mm.py Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org Security Policy: http://www.python.org/cgi-bin/faqw-mm.py?req=show&file=faq01.027.htp
