Antivirus features

As a reactive defense mechanism, protocol rules provide a layer of protection before antivirus signature updates become available. Administrators can filter on known text patterns in malware carriers and drop the connection.

Messages scanned in the Exchange environment can be assigned an antivirus stamp. This stamp identifies which engine did the scanning, which signature was used, and when the message was last scanned.

Antivirus solutions can be more tightly integrated in the Exchange Server 2007 environment. Antivirus solutions have access to the Multipurpose Internet Mail Extensions (MIME) parsers and can scan the message stream in transport (on Edge Transport or Hub Transport servers). Catching viruses in transport helps prevent their delivery and storage in Exchange mailboxes.

Exchange Server 2007 provides integration with Exchange Hosted Services, offering off-site protection against spam and viruses.
