Email::Receiver::AutoGeneratedEmailError

Our emails are being rejected after being received by Discourse. Attempting to problem solve it

/admin/site_settings/category/all_results?filter=block_auto
set to false.

I cannot stop the entire list from being spammed with “auto generated errors” so I had to disable this functionality for now… :frowning:

Email::Receiver::BadDestinationAddress

We're sorry, but your email message to ["example@lists.email.net"] (titled [List] Testing if no more auto-generated messages.) didn't work.

Do you use more than one email address? Did you reply from a different email address? Email replies require that you use the same email address when replying. Alternately, the Message-ID header in the email may have been modified.

In case this might help…
