For Exchange Server 2007
Background scanning capabilities in GSE 7.0 are enhanced using the new features
available in VSAPI v 2.6.
Also, there is a stamping mechanism in case of GroupShield for Exchange Server 2007.
After an email message is scanned, the McAfee
®
Transport Scanner assigns a stamp
to the header of the email message. This prevents the email message from being
re-scanned by Microsoft
®
Virus Scanning API (VSAPI).
The remaining features remain the same as that of Exchange Server 2003.
