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. -- Kevin J.
