The actions associated to conditions of the filtering system. When the condition of a filter is evaluated to true, the associated actions are applied in sequence to the message currently filtered.
Structure of filter_action
Expression to which the action is connected.
Order of the action in the list of actions connected to the expression, starting at 1.
A string that qualifies the action and whose interpretation depends on action_type.
if action_type is 'tag', the value is a tag name. When the tag is part of a hierarchy, the full hierarchy is included in the name, with the substring '->' (dash followed by right angle bracket) as a node separator between levels (example:
Newsletters->artnet monthly for a two-level hierarchy in which
Newsletters is the parent and
artnet monthly is the child tag)
if action_type is 'priority', an action argument of
+=x means to add x (a signed integer) to the current priority of the message, and an argument of
=x means to set the message's priority to x.
if action_type is 'status', the action argument is a substring containing letters from the list:
R, A, T, D.
'R' means to set the read status, 'A' the archived status, 'T' is for the trashed status and 'D' means to discard the message.
if action_type is 'redirect', the action argument is the email address to which the message should be redirected.
