A carrier endpoint filter list contains carrier endpoint patterns. A pattern can match one carrier endpoint or can use wildcards or regular expressions to match multiple carrier endpoints. For each pattern, you select the action that the unit takes on a message when the pattern matches a carrier endpoint in the message. Actions include blocking the message, exempting the message from MMS scanning, and exempting the message from all scanning. You can also configure the pattern to intercept the message and content archive the message to a FortiAnalyzer unit.
