MAIL
When you set up mail rules, you can use the stop processing action alone, that is, as the only action in a mail rule, or you can use it with another action in a rule. Whether stop processing is one of a series of actions or one of a series of rules, no further action is taken after stop processing is encountered. The stop processing rule is especially useful when more than one rule could apply to a message, but you want execution of mail rules to stop after the first action is executed. For example, you could define the following rules:
WHEN Subject contains Marketing THEN Move to folder Marketing Information AND Stop Processing further Rules
WHEN Subject contains Sales THEN Move to folder Sales Information
In this example, if the subject of a message contains "Marketing and Sales," the message is moved to the Marketing Information folder, and then all rule processing stops. If the stop processing action is not present, the message is first moved to the Marketing Information folder, and then moved to the Sales Information folder when the second rule runs.
