For authentication you want SASL - TLS, unless you're issuing and
validating client certificates, is not about authentication.

That said, I do not believe that Fetchmail supports authentication to
the SMTP server.  You should consider not requiring it for loopback
and then configuring fetchmail to use that interface to talk to
postfix.
