The action panel refers to the currently selected condition. It is disabled when no condition is selected. To add an action, select (New action) in the actions list. To remove the currently selected action, use the Del key.
The actions that are currently supported are:
Assign tag: assign a tag to the matching messages. Child tags are expressed flattened as parent_tag->child_tag->grandchild_tag->...
Set status: the argument is a combination of letters: 'R' for read,'A' for archive, all separated by + signs.
Set priority: assign a priority to the matching messages, either as an increment, with the +=X syntax or as an absolute value, with the =X syntax. The priority is an integer number ranging from -32768 to +32767.
Redirect: the argument is an email address to which the matching message is immediately resent.
Stop filters: this is a control-action that instructs the filtering the system that it shouldn't evaluate any more filter rule for the current message.
Set header: set a header field. If the field is already present, the new value will replace the old one in all occurrences of the field, otherwise the field will be added.
Remove header: discard the specified header field. If the field is present multiple times, all its occurrences will be removed.
Set identity: assign a different identity to the message. Each incoming message is associated by manitou-mdx to an identity defined in Preferences/Identities, and each outgoing message is also associated to a sender's identity chosen in the mail composer. The purpose of this action is to override this identity. One practical use is that when replying to an incoming message with an updated identity, the new identity will automatically be pre-selected as the sender of the reply.
Discard: discard the message or put it into the trashcan. The latter is equivalent to having the trashed status.
