MAIL
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 Sales THEN Move to folder Sales Information
