"Take NO action if message contains" option
The Take No Action if Message Contains option allows you to define exceptions that will apply to all the rule sets. Even if all the values in a given Keyword List are detected in a message, no action will be taken if any of the words or phrases appearing in this field are also found.
Like a Keyword List, individual words and phrases are delimited with a comma and connected with an OR operator. An inbound message that matches on two keywords or phrases (e.g., "free offer" and "hot deal") would ordinarily be blocked, however, the message would not be blocked if the message also matched any of the words or phrases specified in the Take No Action if Message Contains field.
Unlike the Keyword List, where multiple rule sets are possible, multiple Take No Action if Message Contains lists cannot be created.
Example: If your policy is to block "Free Offer" email but you do not want to block email that includes the options for users to take themselves off the mailing list, you could include a phrase such as "To remove yourself from this list," in the Take No Action if Message Contains field.
Use a comma at the end of the phrase to delimit it from any words or phrases that may follow.
