Discourse recognizing a bounced email but not updating user bounce score

RBoy · January 30, 2024, 10:39pm

I’m seeing many emails which are bouncing back (hard bounces), discourse is able to parse them and recognize that they’re bouncing but it doesn’t seem be incrementing the user bounce score.

The specific discourse configuration can be seen here : Bounced emails not being detected - #8 by RBoy

Here are the error logs showing that discourse is able to parse the bounced email and recognize that it’s a bounced email.

Email can not be processed: Email::Receiver::BouncedEmailError

This was an example of the weekly summary email that bounced.

Now I understand that due to the lack of a {reply_key} discourse isn’t able to tie the email to a specific topic (does a weekly summary email even have a topic id?), however discourse is able to parse the bounced email and recognize the original recipient email address which bounced.
Therefore, it should therefore increment the bounce score for that user and then eventually stop sending emails to that user.

There are loads of emails like this which bounce back are recognized but then not tied back to the user.
