Running SM 14.2. One of our clients' customers tried to send an e-mail to our client and received the following bounce message:
Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain ----------------.org by mail.----------------.org [IP Address].
The error that the other server returned was:
554 5.7.1 Mail from this email address is not allowed and has been blocked.(no.116 pattern matched)
I've never seen a bounce like this before. What is "no.116 pattern matched"? Is there a file somewhere within SM which lists "patterns"? Any ideas on the cause of the bounce?
