I think this is actually a problem with notmuch, and something that I have complained about in the past. It was previously dismissed, but I still think that it's something we should address. Notmuch should not irrevocably hide messages, just because they cursorily look like a another similar but distinct message. What are ways that we can avoid this? Could notmuch append a string to the message id in the database for the different messages that share an id? Something like "id:foo@bar.com{0}", "id:foo@bar.com{1}", etc? jamie.
