If a message in new has a trailing ":2," in the filename, notmuch will move it to cur whenever tags are modified, even if nothing has changed with tags that are supposed to be synchronized. While it's true that having messages in new with extra info attached violates the maildir spec, it does happen with some clients (I ran into it with offlineimap, and filed a bug https://github.com/OfflineIMAP/offlineimap/issues/80 here, but not sure if or when it will be addressed).
On IRC, it was suggested that it wouldn't really harm anything to consider messages with a trailing ":2," (with no other flags) in new as being equivalent to the info not existing at all. Would this be a possible solution? -doy _______________________________________________ notmuch mailing list firstname.lastname@example.org http://notmuchmail.org/mailman/listinfo/notmuch
