SQL DB Mail unable to relay to Exchange 2013

We just finished upgrading to Exchange 2013. When we use DB mail in SQL we are unable to send mail outside the domain unless we use an Exchange Admins account to send mail.

I have anonymous enabled on the Receive Connector on Exchange 2013.

system.Net.Mail.SmtpFailedRecipientException: Mailbox unavailable. The server response was: 5.7.1 Unable to relay is the message from SQL.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Is this a new rec connector you created? Did you added server into allowed list on that connector? Finally, did you ran this command?
Get-ReceiveConnector “Connector Name” | Add-ADPermission -User “NT AUTHORITY\ANONYMOUS LOGON” -ExtendedRights “Ms-Exch-SMTP-Accept-Any-Recipient”

If answer any one question above it No. Then you need to fix it.

Yes it was a new connector.

I ran the command and still no luck.

I also restarted the Transport Services.
