Email protocols

The IMAP and POP3 protocols are the most widespread protocols used to receive email communication in an email client application. ESET Endpoint Antivirus provides protection for these protocols regardless of the email client used, and without requiring re-configuration of the email client.

You can configure IMAP/IMAPS and POP3/POP3S protocol checking in Advanced setup. To access this setting, expand Web and email > Email client protection > Email protocols.

Enable Email protocols protection – Enables checking of email protocols.

In Windows Vista and later, IMAP and POP3 protocols are automatically detected and scanned on all ports. In Windows XP, only the configured Ports used by the IMAP/POP3 protocol are scanned for all applications, and all ports are scanned for applications marked as Web and email clients.

ESET Endpoint Antivirus also supports the scanning of IMAPS and POP3S protocols, which use an encrypted channel to transfer information between server and client. ESET Endpoint Antivirus checks communication utilizing the SSL (Secure Socket Layer), and TLS (Transport Layer Security) protocols. The program will only scan traffic on ports defined in Ports used by IMAPS/POP3S protocol, regardless of operating system version.

Encrypted communications will be not scanned when default settings are in use. To enable the scanning of encrypted communication, navigate to SSL/TLS in Advanced setup, click Web and email > SSL/TLS and select Enable SSL/TLS protocol filtering.
