The table on the Incoming Mail Policies page shows the names of the filters that have been enabled 
for the engineering policy. 

Commit your changes.

At this point, incoming messages that match the user list for the engineering policy will not have MP3 
attachments stripped; however, all other incoming messages will have MP3 attachments stripped. 

It is not necessary to specify a condition when creating a content filter. When no action is defined, 
any actions defined will always apply in the rule. (Specifying no action is   equivalent to using the 

true()

 message filter rule — all messages will be matched if the content filter is applied to a policy.) 

If you do not assign a custom user role to a content filter, the content filter is public and can be used 
by any delegated administrator for their mail policies. See 

more information on delegated administrators and content filters.

Administrators and operators can view and edit all content filters on an appliance, even when the 
content filters are assigned to custom user roles.

When entering text for filter rules and actions, the following meta characters have special meaning 
in regular expression matching: 

. ^ $ * + ? { [ ] \ | ( )

If you do not wish to use regular expression you should use a '\' (backslash) to escape any of these 
characters. For example: "\*Warning\*" 

When you define more than one Condition for a content filter, you can define whether all of the 
defined actions (that is, a logical AND) or any of the defined actions (logical OR) need to apply in 
order for the content filter to be considered a match.
