Reading through the various posts on AV, there might be some confusion. There are 3 entirely different Anti-Virus software that can be loaded on an Exchange server. 1. Normal AV scanning, such as SAV 8.0 and NAV 7.x and so forth. This is to protect the server itself. This does nothing to check e-mails flowing through Exchange. 2. AV SMTP server. This is a product that would act as a go between between the Exchange SMTP Server and the Internet. Only AV products specifically designed to work like, or a gateway service, can scan messages going to or coming from Exchange. 3. AV scanning of the Information Store. AV products that can scan the store work with through the Exchange API. Only those products specifically designed and documented to work in this way will scan and protect the Information Store. So, for complete protection, you need to have a regular AV software such as SAV 8.0 to protect the server itself AND either a AV SMTP gateway or an AV Exchange Information Store scanner.
