Version: 1.9.6 (using KDE KDE 3.5.8) Installed from: SuSE RPMs OS: Linux so sometimes it works sometimes it doesn't. mostly it doesn't. example: Several message from the same bugzilla bug, no subject change, did not go into the same thread in kmail (they display in the same thread in the webmail interface). this was reproducable on several bugzilla bugs.
Please check that the bugzilla mails have a correct In-Reply-To: header and that the parent message with the same id exists in the folder. If this is really the case, this is a bug, otherwise KMail can't don anything about it.
I have 3 messages from kde's bugzilla with this lines in the header. If you'd like I can attache full header info or even all 3 emails. In-Reply-To: <20050227203648.100397.noh.way.jose@dsl.pipex.com> The Message-ID line doesn't match on any of them though, and doesn't match the in reply to line. I assume that because the Message-ID and In-Reply-To: lines aren't equal they aren't in the same thread even though all 3 have the same In-Reply-To info. Perhaps kmail should just check to see if the In-Reply-To information is the same, if that's the same shouldn't they belong to the same thread? regardless of whether you still have or ever had the orignal email.
>Perhaps kmail should just check to see if the In-Reply-To information is the same, if that's the same shouldn't they belong to the same thread? Well, they are in the same thread, but still, you don't know the message parent, so there is no way to thread them properly. I'll close this as WONTFIX, as I see no logical way KMail could thread messages with missing parents.
couldn't it be done by date, as a fall back behavior, if there is no parent message.
>couldn't it be done by date, as a fall back behavior, if there is no parent message. Yes, but that is again already reported: bug 107450.
