After changing the Symantec Messaging Gateway (SMG) IP address via Administration > Configuration > host > Ethernet, messages with the Suspect Virus verdict are no longer delivered to the Suspect Virus Quarantine and are not delivered to the final recipient.
The change to the scanner IP address is not reflected in all configuration files so messages with the Suspect Virus verdict are still being routed to the original IP address.
The issue with changes to the Control Center IP address not being propoagated to all configuration files, in this case the MTA suspect virus mail route, has been addressed with the 10.6.6 release. Following 10.6.6, changes to the Control Center IP address will be reflected in the internal MTA mail routes.
For systems which are alreading in this state, the underlying issue will not be corrected by an upgrade to 10.6.6 but the following process will update the MTA confuration:
Following this process will update the MTA configuration for all scanners connected to the SMG Control Center including the local scanner on combined Control Center / Scanner systems.
