email-analysis url-dynamic-analysis domain-whitelist

Adds or deletes a custom domain whitelist for URL Dynamic Analysis.

You can add a domain to a custom whitelist or delete a domain from a custom whitelist. A domain whitelist allows you to bypass domains that are considered to be nonmalicious. The Email Security — Server appliance will not analyze a URL within an email message body for malicious content if it contains a whitelisted domain. You can add up to 100 domain whitelist entries to the appliance database. You can add or delete each custom domain separately.

Note

Use the no email-analysis url-dynamic-analysis domain-whitelist command to completely delete all domains at one time.

Note

You can use a wildcard domain URL to a custom whitelist. Use a backslash (\) to escape special regular expression characters.

For details about how to add or delete a custom whitelist for URL Dynamic Analysis, refer to the "Email MTA Configuration" chapter of the Email Security — Server User Guide.

Note

URL Dynamic Analysis is also called Dynamic URL Analysis or DUA.
