Save a copy of cleaned and deleted attachments in mail quarantine

A copy of the original file attachment will be stored in the mail quarantine.

Use custom text to replace deleted attachments

When enabled, you can specify custom text that replaces deleted attachments.

Add notification to the body of scanned messages offers three options:

•Do not append to messages—Information will not be added

•Append to infected messages only—Affects only infected messages

•Append to all messages (does not apply to internal messages)—All messages will be marked

Modify subject

When enabled, you can modify the templates added to the subject of infected messages, spam or phishing messages.

Template added to the subject of infected messages

ESET Mail Security will append a notification tag to the email subject with the value defined in the Template added to the subject of infected messages text field (pre-defined default text is [found threat %VIRUSNAME%]). This modification can be used to automate infected message filtering by filtering emails with a specific subject, for example using Rules or alternatively on the client side (if supported by the email client) to put those email messages in a separate folder.

Template added to the subject of spam messages

ESET Mail Security will append a notification tag to the email subject with the value defined in the Template added to the subject of spam messages text field (pre-defined default text it [SPAM]). This modification can be used to automate spam filtering by filtering emails with a specific subject, for example using Rules or alternatively on a client side (if supported by the email client) to put those email messages into a separate folder.

Template added to the subject of phish messages

ESET Mail Security will append a notification tag to the email subject with the value defined in the Template added to the subject of phish messages text field (pre-defined default text it [PHISH]). This modification can be used to automate spam filtering by filtering emails with a specific subject, for example using Rules or alternatively on a client side (if supported by the email client) to put those email messages into a separate folder.
