Subject Line: Delivery Status Notification (Failure)
Message: Delivery to the following recipient failed permanently:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 #5.1.0 Address rejected email@example.com (state 14).
The Cause: There is no “mail.domain.com” in the dns system. In my case I was sending the mail via an alias (it was a notification email from the web server). The receiving mail server sees the email as forged and bounces it.
The Solution: Go to the dns system and create a mail.domain.com and point your MX records to that. It’s a bit silly, but it has to be done that way.
