=head1 NAME

RT::Interface::Email::Auth::MailFrom - The default mail gateway authenticator

=head1 SYNOPSIS

This is the default authentication plugin for RT's email gateway; no no
other authentication plugin is found in L<RT_Config/@MailPlugins>, RT
will default to this one.

This plugin reads the first address found in the C<Reply-To>, C<From>,
and C<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.
