Configuring subject line content filtering in Symantec Protection Engine
This topic explains the options that are configured using the Core server with user interface mode. to work with the Core server only mode.
If your client uses the ICAP protocol or the Native protocol, you can configure Symantec Protection Engine to block messages by the subject line. You can use this feature to handle new-borne threats for which a threat definition has not been created. You can also use this feature to filter mail messages for inappropriate or confidential information or potential spam.
Symantec Protection Engine scans the subject lines of incoming mail messages for the text string that you specify. You can use wildcard characters when you are not sure of the exact subject line. Symantec Protection Engine ignores any white space (tabs or spaces) at the beginning of the subject line. It also ignores any white space that you enter at the beginning of your text string.
Symantec Protection Engine automatically encodes and saves the text strings in Unicode/UTF-8 when you apply your changes in the console.
