We are running discourse for a while now and everything was working just fine. However since recently we’ve noticed increased amount of outgoing email. Short investigation discovered an infinite loop:
- We are mailing user about new post, as expected.
- User has removed his email address, email bounces and we receive an email from email@example.com
- We received auto-generated email, so we reply to it with EmailRejectAutoGenerated message.
- firstname.lastname@example.org opens a new support ticket and informs us about this with auto-generated message (with support ticket number, so each email has different subject)
- GOTO 3
At the moment we have disabled all the emails, most likely we will allow outgoing emails and disable incoming emails, but this is not ideal. Is there a way to disable only EmailRejectAutoGenerated emails?
