550 5.7.1 RESOLVER.RST.AuthRequired; authentication required
The web server in DMZ is not able to send mail to a distribution group in our Exchange 2010. I'm sure the receive connector has been set to allow delivery of internal emails from anonymous users with this command:
Get-ReceiveConnector "RelayWeb” | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Autho
and from the log tracking I can see the email did get through the connector but then failed in routing to this distribution group. The error is:
550 5.7.1 RESOLVER.RST.AuthRequired;
What could be wrong? Could a distribution group be set up to only allow authenticated users to send mail? How to resolve the issue?
Please help. Thanks.

Double check you receive connector in the Exchange management console and make sure it's not set up for authentication see below:

But it should be some other issue than of the receive connector as I can see from the log that the email did get through the connector. (see attached.)
As I can see, it is more like a distribution group being set up to only allow authenticated users to send mail. But if that is the case, how to resolve it?
