Resolution

Mail Security can scan messages and their attachments to detect the following:

Mail Security takes the actions that you specify in the respective policies when a violation is detected.

See About Mail Security policies

Mail Security contains a decomposer that extracts container files so that they can be scanned. The decomposer continues to extract container files until it reaches the base file or until it reaches its extraction limit. If the decomposer reaches the set limit before the base file is reached, the scanning process stops. Mail Security then logs the violation to the specified logging destinations, and the file is handled according to Unscannable File Rule.
