It is not just the Subject: but also the In-Reply-To: and References: headers. A good MUA (mail reader) will use these to deduce what is in reply to what and have the ability to show an email 'thread'. I use mutt which does this. For instance the email that I am replying to has the following headers: In-Reply-To: <0e3e9efd-410d-4f63-9ddf-5dc1656f8...@busby.net> References: <Z4UiQnQqvtWHX5pZ@q957> <z4uoevn0kwoa9...@tuxteam.de> <3jrf5l-55uu....@q957.zbmc.eu> <20250113113710.55158b0a@hawk.localdomain> <v97g5l-h43v....@q957.zbmc.eu> <20250113201431.gf27...@wooledge.org> <pmeg5l-4n6v....@q957.zbmc.eu> <20250113161313.62a7697b@hawk.localdomain> <cah8yc8kavpkexoddrhsmb9cbpmeufpk7xqgwwtfyt+gb3vu...@mail.gmail.com> <0e3e9efd-410d-4f63-9ddf-5dc1656f8...@busby.net> > Does anybody read signatures any more?
