Kaspersky Endpoint Security 11 for Windows

Mail Threat Protection

April 25, 2024

ID 34268

The Mail Threat Protection component scans the attachments of incoming and outgoing email messages for viruses and other threats. The component provides computer protection with the help of anti-virus databases, the Kaspersky Security Network cloud service, and heuristic analysis.

Mail Threat Protection can scan both incoming and outgoing messages. The application supports POP3, SMTP, IMAP, and NNTP in the following mail clients:

  • Microsoft Office Outlook
  • Mozilla Thunderbird
  • Microsoft Outlook Express
  • Windows Mail

Mail Threat Protection does not support other protocols and mail clients.

Mail Threat Protection may not always be able to gain protocol-level access to messages (for example, when using the Microsoft Exchange solution). For this reason, Mail Threat Protection includes an extension for Microsoft Office Outlook. The extension allows scanning messages at the level of the mail client. The Mail Threat Protection extension supports operations with Outlook 2010, 2013, 2016, and 2019.

The Mail Threat Protection component does not scan messages if the mail client is open in a browser.

When a malicious file is detected in an attachment, Kaspersky Endpoint Security adds information about the performed action to the message subject, for example, [Message has been processed] <message subject>.
