analysis custom whitelist regex url

Adds a rule to a custom whitelist based on the RegEx URL.

A whitelist allows you to control which messages that contain an attachment can be bypassed based on the matched known rule entries. No further analysis is performed. The appliance will not analyze an attachment within an email message for malicious content if it contains the regex URL that you defined and added to the appliance database.

You can add up to 10,000 whitelist entries to the appliance database.
