I think of this as keeping a mapping from "rfc822 message-id" to "internal thread-id". I think you are using different words to say the same thing. > When deleting messages, always retain the message-id and stableurl hashes > for that message in the mapping.

If you are going to have a record of the deletion (i.e. you can keep a deleted message around in some form), this problem becomes much easier. I thought this desire was to have stable urls and threads when you rebuild and a message is missing. Absolutly if there is a message 'deletion' feature, it should delete the message contents but leave a 'stub' that links the message-id and references/in-reply-to, so it can help hold the thread together during a rebuild. My memory is foggy, but I think we used a technique like this in Yahoo Groups. _______________________________________________ Mailman-Developers mailing list Mailman-Developers@python.org http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
