Symantec Mail Security 4.5 for Microsoft Exchange protects an Exchange 2003 server. The Auto-Protect option; “Scan SMTP messages leaving the server” is enabled. Email is accumulating in the “Messages pending submission” queue. This server’s primary role is an SMTP gateway or Front-End server. The local Information Store service is disabled. The Mailbox Store is not mounted.
The Auto-Protect option "Scan SMTP messages leaving the server" on Exchange 2003 uses Microsoft's VSAPI 2.5 TransportAVAPI protocol. This protocol requires a local store to be available for scanning of SMTP traffic. If no store is available to the TransportAVAPI for scanning, all messages will be stuck in the SMTP queue “Messages pending submission”. To submit these items for scanning once the store is remounted, use the “Force connection” option from Exchange System Manager.
TransportAVAPI Scanning Details
Microsoft's TransportAVAPI uses the SMTP mailbox as a temporary location for scanning SMTP messages for viruses. The SMTP Mailbox name uses the syntax:
The individual message items (message body/attachments) are submitted to SMS for Exchange 4.5 from a subfolder of this mailbox. The subfolder is called:
Selecting an action, like quarantine, when an item is viral causes a log entry and alert. The log entry and alert show the violating item location is the special folder.
