↳ In-reply-to » (#o) @prologic this was your first twtxt. Cool! :-P

@quark@ferengi.one Ahh, I see:

Message-Id: <o6dsrga>

That’s an older format that was used before jenny version v23.04. It should look like this nowadays:

Message-Id: <o6dsrga@twtxt>

Changelog entry from back then:

v23.04  2023-04-19
  [Changed]
  - The format of the "Message-Id" and "In-Reply-To" headers has
    changed. They now need an "@twtxt" suffix to be more compliant with
    RFC(2)822. This fixes issues when using aerc
    (https://aerc-mail.org/) as a frontend instead of mutt.

    If you want to retain compatibility with existing files in your
    maildir, you must manually add this suffix to these headers. (Or go
    ahead and re-sync everything.)

I guess I could have added backwards compatibility to the code. Maybe I’ll fix that later. 🤔
