Gregor Zattler mentioned some problems with threading at id:20120126004024.GA13704 at shi.workgroup
After some off list discussions, I believe I have a smaller test case. The attached maildir contains 24 messages from the org mode list. According to notmuch, these form one thread, but I can't figure out exactly why. It seems like the chronologically first two messages should be a seperate thread. There are several of the infamous malformed ME-E In-reply-to headers, but each of these messages also has a References header; this seems to indicate a case missed by commit cf8aaafbad68. -------------- next part -------------- A non-text attachment was scrubbed...
