RT::Interface::Email::Auth::MailFrom - The default mail gateway authenticator
This is the default authentication plugin for RT's email gateway; no no other authentication plugin is found in "@MailPlugins" in RT_Config, RT will default to this one.
This plugin reads the first address found in the
Sender headers, and loads or creates the user. It performs no checking of the identity of the user, and trusts the headers of the incoming email.
