RT::Interface::Email::Filter::TakeAction − Change metadata of ticket via email
This filter action is built to work with the email plugin interface for RT 4.2 and earlier. As such, it implements the "GetCurrentUser" method and provides all functionality via that plugin hook.
The email plugin interface is changed in RT 4.4. For details on the implementation for RT 4.4 and later, see RT::Interface::Email::Action::CommandByMail.
Returns a CurrentUser object and an appropriate AuthLevel code to be interpreted by RT’s email gateway.
