Configuring MMS file filtering
To apply MMS file filtering you must begin with a file filter list. You can create your own list or use the built-in patterns list. You then must create the file filter, then add the file filter list to an MMS profile, and then add the MMS profile to a security policy. The MMS profile, and the corresponding file filter then applies to the traffic accepted by the security policy.
The following procedure creates a file filtering list called MMS_file_filter that is used in the MMS profile called filtering_profile. The filter will be applied to all MMS message types.
