All inbound mail stuck in Submission Queue with a delivery type of Unknown and error A Local Loop was Detected
My email organization consists of two email servers: Exchange 2013, Oracle Messaging. The servers are in two different geographic locations.
The Oracle messaging is the primary email server (orc1.MyDomain.com)
The Exchange server (loc2-ex.MyDom2.local)
A routing rule on the Oracle messaging server forwards MyDom2 user email (changes the email address from @MyDomain.com to @loc2.MyDomain.com) to the remote Exchange server.
On the Exchange server, the domain MyDomain.com is set for internal relay. MyDom2.local and loc2.MyDomain.com are set at Authoritative.
Users on the Exchange server can send Internet bound email that is delivery as expected to outside domains. Email between exchange users and inbound internet email gets delivered to the Exchange server but is not posted to the user's email. Instead it remains in "Submission queue" (delivery type "undefined", status "ready") Each message's last error is "A local loop was detected" (SCL "-1", Queue ID "Loc2-EX\Submission", Message Source Name "SMTP: Client ProxyLoc2-EX")
How do I get Exchange to deliver emails?
Here are the settings for Accepted Domains, and the Send and Receive Connectors:
