What's interestng is that neither Gnus, nor my previous client seem to
be sending a User-Agent header, so that can't be the issue.

I've compared the headers from my various clients.

Here are the headers from an email sent from neomutt (not marked spam):

Here are the headers from an email sent from FairEmail (not marked

Here are the headers from an email sent from emacs (marked as spam):

From: Jonathan Lamothe <jonathan@jlamothe.net>
To: [redacted]@gmail.com
Subject: Emacs Test
Date: Sat, 11 Apr 2026 20:46:09 +0000
Message-ID: <874ilh6x9t.fsf@posteo.de>
MIME-Version: 1.0
Content-Type: text/plain


Things I've unsuccessfully tried:

- Hacknig emacs to change the Message-ID so that the part before the @
  is a SHA256
- Ensuring that the Content-Type header contais an encoding i.e.:
  text/plain; charset=UTF-8

Also worth noting: replies sent to email originating from Gmail seem to
be passing the spam filter.
