Searching Embedded Emails for Key Text

Emails can contain embedded messages, and can even contain embedded messages which themselves contain further embedded messages! To recursively decompress, extract and search the text content of these embedded emails can cause a performance slowdown.

To alleviate this problem, you can specify the maximum depth of nesting supported by CA Data Protection. To do this, edit the Maximum Depth of Nested Zip Files and E-mails setting in the user policy System Settings folder.

For example, if you set a maximum depth of 2, CA Data Protection drills down two levels of nesting to analyze embedded messages. In practice, this means it searches the text content of a message embedded inside a message that is itself embedded inside an email. If CA Data Protection detects a further level of nesting, it does not search the messages embedded inside this further embedded message.

Note: This policy setting also covers nested zip files.
