Error in Email listener with MSMQ

I came across this error in an ITSM 504 SP1 Patch 0606 system when implementing the Email Listener.

Error occured while reading and processing the email(s). Reason: Queue is not registered in the DS.

The listener processes the files and creates a Before and After Transform XML file but it doens't add the object into the system.

The following workaround will cause issues with business rules but will get the email listener working.

After Upgrade to 504 sp1 I receive the following Error Queue is not registered in the DS

Issue
Error Queue is not registered in the DS while creating new Incidents in application.
