Mailbox database protection
The mailbox scanning process is triggered and controlled by the Microsoft Exchange Server. Emails in the Microsoft Exchange Server store database are scanned continuously. Depending on the version of Microsoft Exchange Server, the VSAPI interface version and the user-defined settings, the scanning process can be triggered in any of the following situations:
•When the user accesses email, for example, in an email client (email is always scanned with the latest virus signature database)
•In the background, when use of the Microsoft Exchange Server is low
•Proactively (based on the Microsoft Exchange Server’s inner algorithm)
The VSAPI interface is currently used for antivirus scan and rule-based protection.
