Title: Support user selected delivery method instead of smtp config.

This is mostly a convenient way to enable sendmail (instead of using
:address => "localhost" as config).

Also, when using sendmail directly there is no need for a :from address
since sendmail will use an appropriate one automatically (if configured
correctly).
