This change allows email-clients to show threaded views of mails as expected. Apparently most algorithms expect the message ids of mails in the Reference-header-field to be sorted such that they build a traversal through the thread, so the oldest (original) message being first, then its child, grandchild and so on until it arrives at the message id that the "new" mail (that is to be sent) is the reply to. MSGA [1] +- Re: MSGA [1-1] | +- Re: Re: MSGA [1-2-1] | +- Re: Re: MSGA [1-2-2] +- Re: MSGA [1-1] If the stuff in brackets would be the message ID, the References-Header field of a message that is a reply to [1-2-1] should look like: References: 1, 1-1, 1-2-1 Discussion took place in: https://meta.discourse.org/t/e-mail-threading-in-ml-mode-does-not-work-in-thunderbird Main information taken from: https://www.jwz.org/doc/threading.html |
