Your mails lack headers like "In-Reply-To:" or "References:", which should tell the Message Id of the mail to which you answer resp. some or all IDs of the thread. (My "References:" only has the Id of the mail to which i answer.) This is already defined in ye olde RFC 822, which is now replaced by https://datatracker.ietf.org/doc/html/rfc2822 The headers in the mail, where Markus Schönhaber complained about the broken threading shows: References: <CAM-dBgohVfdSWPj=hpaiabh8qczvo1+fummptzn9bo_fwjz...@mail.gmail.com> In-Reply-To: <CAM-dBgohVfdSWPj=hpaiabh8qczvo1+fummptzn9bo_fwjz...@mail.gmail.com> Message-ID: <33ea0533-ae82-c939-1b91-77828f191...@list-post.mks-mail.de> which correspond to the Message Id in your mail From: jr <creature.eter...@gmail.com> Date: Wed, 21 Sep 2022 16:29:07 +0100 Message-ID: <CAM-dBgohVfdSWPj=hpaiabh8qczvo1+fummptzn9bo_fwjz...@mail.gmail.com> A properly threaded reply to the mail of Markus Schönhaber would have something like References: <33ea0533-ae82-c939-1b91-77828f191...@list-post.mks-mail.de> In-Reply-To: <33ea0533-ae82-c939-1b91-77828f191...@list-post.mks-mail.de> Have a nice day :) Thomas
