RT 4.2 removed the ability to speak directly to an SMTP server -- as
operating in such a configuration meant that outgoing mail was lost if
there was ever connectivity problems to the SMTP host.  A local MTA is
meant to solve precisely that problem, which is why RT relies on it.

In short, that's no longer a supported configuration, to stop users from
shooting themselves in the foot.

Taking a step back, you really should look at your MTA's configuration
and error logs.  All of the workarounds and questions you're asking are
about RT -- but RT is not actually the cause of your problem.  Solve
your actual problem, and the symptoms will go away.
