Email protection

Email protection provides control of email communication received through the POP3 and IMAP protocols. When examining incoming messages, ESET Endpoint Security for macOS uses the advanced scanning methods included in the ThreatSense scanning engine. Scanning of the POP3 and IMAP protocol communications occur when any email client used. The following settings are available:

ThreatSense Engine: Setup – Advanced virus scanner setup enables you to configure scan targets, detection methods, and so on. Click Setup to display the detailed scanner setup window.

Append tag message to email footnote – After an email is scanned, a notification containing the scan results can be appended to the message. Tag messages cannot be relied on exclusively because the tags may be omitted in problematic HTML messages and can be forged by some viruses. The following options are available:

oNever – No tag messages is added.

oTo infected email only – Only messages containing malicious software are tagged as checked.

oTo all scanned email – ESET Endpoint Security for macOS appends tag messages to all scanned email.

Append note to the subject of received and read infected email – Select this check box if you want email protection to include a virus warning in the infected email. This feature allows for simple filtering of infected emails. This feature also increases the level of credibility for the recipient, and if an infiltration is detected, it provides valuable information about the threat level of a given email or sender.

Template added to the subject of infected email – Edit this template to modify the subject prefix format of an infected email. Following are available template fields you can use and their meanings:

o%avstatus% - Adds the email infection status (for example: clean, infected, and so on).

o%virus% - Adds the name of the threat.

o%product% - Adds the name of your ESET product (in this case - ESET Endpoint Security for macOS).

o%product_url% - Adds the  ESET web site link (
