> The plaintext record of the email sent to Discourse from Mailman (`IncomingEmail`) is available [here](https://paste.lib3.net/lavamind/2026-01-12-6kqgZqUPAyl_aXR9SN1C538kPeOR6FA4DM6ReXtGUNc/stdin.txt)

Running that through `Email::Receiver.new(rawmessage).select_body` returns:

```plaintext
=> ["", "", 2]

```

so I’m pretty confident what’s happening here is that Discourse is incorrectly selecting an empty plain/text portion as the message body, probably this one:

```plaintext
--Sig_/gizYC_1dGsAzUHvksdaMIe2
Content-Type: text/plain;
 charset=UTF-8
Content-Transfer-Encoding: 7bit

```

which would be an invalid post.

We’ll need to do a bit of investigation on this and probably use it as a test case.
