I am not sure which one of these you need. I have set both
and my Sendmail connects to smart host's TCP port 587.

define(`ESMTP_MAILER_ARGS', `TCP $h 587')dnl
define(`RELAY_MAILER_ARGS', `TCP $h 587')dnl

Sendmail will use STARTTLS automatically as long as
your receiving server advertises to support it.
