It is trouble in web URLs, not in E-Mail. RFC5322 says that the payload string of Message-ID is a msg-id, which consists of [CFWS] "<" id-left "@" id-right ">" [CFWS]. The offending slashes appear in the id-left part of the message id in https://lists.debian.org/debian-user/2023/04/msg01201.html The RFC specifies id-left as dot-atom-text (or an obs-id-left which is legacy). dot-atom-text consists of atext and ".". atext is allowed to contain "/". So the message id conforms to e-mail specs. But the list archive software does not convert the message id into a usable URL. I found the archived message by entering "ZEyj9UUSAx+/YbG/@tuxteam.de" at https://lists.debian.org/msgid-search/ which is part of the List-Archive: header of all debian-user e-mails. Have a nice day :) Thomas
