You cannot release mail from either the Suspect Virus Quarantine or Content Filtering Quarantine in Symantec Messaging Gateway (SMG).
Cannot manually release any messages from the Suspect Virus Quarantine or Content Filtering Quarantine.
Messages do not automatically release from the Suspect Virus Quarantine or Content Filtering Quarantine as scheduled.
Messages can be released from the Spam Quarantine.
SMG Scanner and Control Center are not installed on the same computer.
Scanner is located in the DMZ (demilitarized zone), outside the firewall
Control Center is located in the production network, inside the firewall
Not all selected messages could be released. See the Control Center logs for details.
The firewall is blocking communication from the SMG Control Center to the Scanner on port 25.
Ensure that communication between the SMG Control Center IP address is allowed to the Scanner IP addresses on TCP port 25.
When the SMG Control Center is located inside the firewall, and the Scanner is located outside the firewall, port 25 must be open between the Control Center and the Scanner for Suspect Virus and Content Filtering Quarantine release to operate correctly.
Note: Messaging Gateway handles messages in the Spam Quarantine differently from messages in the Suspect Virus Quarantine. Messages in the Spam Quarantine are released and delivered directly from the Control Center to the configured internal mail server.
