You can create Content Manager rules to filter incoming or outgoing mail based on a text string or pattern in message headers or content. By checking against a word list, you could filter out profanity, or messages with political content, or a particular message which is not blocked by other filters.

To add a new Content Manager filter:

1. Go to the Content Manager Filter List page for the organization that contains your users.
2. Ensure that the Content Manager Filter Status is On. If not, enable Content Manager.
3. Click the Add Filter link. The Add Filter page appears.
4. Under Filter Name, enter a descriptive name for the filter in the box.
5. Under Rules, in the Match drop-down list, choose whether Content Manager executes this filter’s disposition if an email message contains a match for any rule or all rules you specify.
6. Under Rules, specify up to three rules for this filter. For details about the options for creating rules, see Filter Rules.
7. Click Save.

All mail for that organization will immediately be filtered according to the rules of the filter you created.

Note: Create text rules carefully. Be sure that you don't accidentally quarantine valid messages. Consider using the Log and Deliver option for a trial period to find out what messages would have been blocked before you implement a new filter. This takes extra time but helps to prevent unexpected quarantining.
