Hi I think notmuch links two messages into the same thread if they have an in-reply-to or reference header in common: i.e the messages reference a common parent message. (See comment in lib/database.cc "Even before a message is added, it's pre-allocated thread ID is useful so that all descendant messages that reference this common parent can be recognized as belonging to the same thread.") As far as I can see your grep tests haven't checked for that. Also, could you email me the mbox you had (I think you said that it was a mailing list so all public) and I will take a look? Thanks Mark
