I tried poking around a bit more and maybe I was too hasty in blaming gmail :) For me, the failure of "A T" is arising because the 'references header in the emails within a thread are not right. In particular, this header is supposed to include most of the message-ids in the thread that the message is aware of (e.g. if its the 4th message in a chain of replies this header should contain the message-ids of all the prior messages; if this list of prior messages is extremely long the spec allows dropping part of it). But for the cases where "A T" fails this header contains only a /single/ message-id, that of the immediate prior email. This prevents the full thread from being found. The most likely explanation is that the mailer used by the sender is not adding the full references header. I assumed it was gmail that was responsible, but a closer look at the messages on which "A T" fails shows that they were all sent by the iphone mailer. So while I haven't done any exhaustive testing, this is my current culprit. But I am curious if others are seeing the same thing. So jibstyle maybe you can help with some testing? First, for the purposes of the test can you 1. Set 'gnus-refer-thread-use-search to 'nil, 2. Enter the "[Gmail]/All Mail" group and find an article late in the thread on which you know thread referral fails to find the full thread. Examine the headers of this article (by typing C-g when point is on the article in the summary buffer) and see what is in the References header? And what mailer was used to send the message? For example when I do this I find the headers contain In-Reply-To: <CAKfuin7MPjj5m@mail.gmail.com> References: <CAKfuin7MPjj5m@mail.gmail.com> X-Mailer: iPhone Mail (19E258) which shows that the References header only contains the immediately prior email's message-id but not that of any of the other messages.
