Our Ironports do such a great job at stopping viruses that for the past year our ScanMail for Exchange product has not found a single virus on our Exchange cluster. The only thing ScanMail finds are password-protected zip files. We cannot afford to renew our licenses for ScanMail and every big AV vendor out there licenses per mailbox, which puts the cost out of reach for us at 7000+ mailboxes. I'm wondering how many other Ironport customers forgo an additional AV product to scan Exchange? Of course we have a server-based product running to protect the OS on our Exchange servers. Thanks.
