Bounced emails not being detected

Absolutely

Email parsing setup:

Email sending setup:

  • The email sent by Discourse goes from discourse@xxx.com via a dedicated domain SMTP server setup for discourse (using the discourse domain address).
  • Any replies or when email bounces back, the domain SMTP server forwards the email to discourse.xxxx@gmail.com. This domain SMTP server cannot recognize the + addressing, so if I include the reply_key in the reply to email address, it’ll get dropped by the domain SMTP server. I can only set rules to forward discrete/unique incoming email addresses.
  • The discourse forum then uses POP via GMail to access those forwarded replies/bounced emails and parses them.

Does this help?
