Based on the message scan results, ESET Endpoint Security can move scanned messages or add custom text to subject. You can configure these settings in Advanced setup > Protections > Email client protection > Mailbox protection > Response.

Email client antispam in ESET Endpoint Security enables you to configure the following parameters for messages:

Add text to email subject—Enables you to add a custom prefix string to the subject line of messages that have been classified as spam. The default Text is "[SPAM]".

Move to spam folder—When enabled, spam messages will be moved to the default junk email folder, and messages reclassified as not spam will be moved to the inbox. When you right-click an email message and select ESET Endpoint Security from the context menu, you can choose from applicable options.

Move to custom folder—When enabled, spam messages will be moved to a folder specified below.

Folder—Specify the custom folder where you want to move infected emails when detected.

If there is a message containing detection, by default, ESET Endpoint Security attempts to clean the message. If the message cannot be cleaned, you can choose an Action to take if cleaning not possible:

  • No action—If enabled, the program will identify infected attachments but will leave emails without taking any action.
  • Delete email—The program will notify the user about infiltration(s) and delete the message.
  • Move email to the Deleted items folder—Infected emails will be moved automatically to the Deleted items folder.
  • Move email to folder (default action)—Infected emails will be moved automatically to the specified folder.

Folder—Specify the custom folder where you want to move infected emails when detected.

Mark spam messages as read—Enable this to mark spam as read automatically. It will help you to focus your attention on "clean" messages.

Mark reclassified messages as unread—Messages originally classified as spam but later marked as "clean" will be displayed as unread.

After an email has been checked, a notification with the scan result can be appended to the message. You can elect to Append tag messages to received and read email or Append tag messages to sent email. Be aware that on rare occasions tag messages may be omitted in problematic HTML messages or if messages are forged by malware. The tag messages can be added to received and read email, sent email or both. The following options are available:

  • Never—No tag messages will be added.
  • When a detection occurs—Only messages containing malicious software will be marked as checked (default).
  • To all email when scanned—The program will append messages to all scanned email.

Update subject of received and read email / Update subject of sent email—Enable this option to add custom text specified below to the message.

Text to add to subject of detected email—Edit this template if you want to modify the subject prefix format of an infected email. This function will replace the message subject "Hello" to the following format: "[detection %DETECTIONNAME%] Hello". The variable %DETECTIONNAME% represents the detection.
