Good Morning,
We have one distribution gorup that we cant send emails from outside network. everything else is just fine. I double checked and the option 'Senders inside and outside of my organization' is selected too.
what can be the issue with this. its a new distribution group. every other distribution group is just fine.
here is the message we get when sent emails from outside to this distribution group:
Final-Recipient: rfc822;info@mydomain.com
Action: failed
Status: 5.5.0
Diagnostic-Code: smtp;550 #5.1.0 Address rejected.
