20 Action (filtering/processing rules)
24 An action is something that is performed on a message when it matches
25 the rule conditions. A typical action is moving the message to a
26 particular folder. See also <xref linkend="gt_condition_rules" />.
30 <varlistentry id="gt_actions">
36 Actions are user-defined commands that can be applied to a message, or
