Awesome!  The stunnel trick works!

1) I set up /etc/stunnel/stunnel.conf as in the Fedora Wiki example (I used port 25025).

2) I then ran "stunnel" from root.
    [I'll have to put that in rc.local before I reboot.]

3) In sendmail.mc, I used:
define(`SMART_HOST', `relay:[localhost]')
define(`RELAY_MAILER', `smtps')
define(`RELAY_MAILER_ARGS', 'tcp $h 25025')

4) Changed my /etc/mail/authinfo file to remove the hostname after AuthInfo:

5) ran make in /etc/mail
   (this should remake both authinfo.db and sendmail.cf)

6) restarted sendmail

And my first test email got delivered to my ISP address!

Thanks to all for the info.
