Mail threat protection

The Traffic Security component scans mail in 32-bit and 64-bit editions of Microsoft Outlook (2010, 2013, 2016, 2019, and 365). Mail threat protection is provided through a Microsoft Outlook Add-in that is installed separately from Kaspersky Security for Windows Server components.

Mail threat protection includes:

• Incoming email scanning (including encrypted email).
• Virus email scanning.
• Virus scanning of attachments (including packed objects).
• Anti-phishing email scanning.
• Anti-phishing scanning of attachments (including packed objects).

If a threat is detected, Kaspersky Security for Windows Server:

• Permanently deletes infected attachments.
• Modifies the infected message body. The original infected message body is attached as an HTML page along with information about the threat. If a phishing link is detected, the original infected message body is attached in TXT format along with information about the threat.
• Logs a Mail threat detected event.

Kaspersky Security for Windows Server scans emails when they are opened, not when they are received by the protected device. The scan is performed only once when they are first opened. The scanned emails and attachments are stored in a cache until Outlook restarts. After a restart, emails are scanned again when they are opened.

If Microsoft Outlook mail client is running during installation of the Add-in, you must restart it after completion of the installation.

Kaspersky Security for Windows Server performs the mail threat protection only when the Traffic Security task is running and the Enable mail threat protection check box is selected. The check box is selected by default. You can configure the mail threat protection via the Administration Plug-in, Application Console, or Web Plug-in.
