Based on googling, I added the following to my config.mc:
define(`SMART_HOST',`[smtp.biz.rr.com]')
FEATURE(`authinfo', `hash /etc/mail/authinfo')dnl
then generated the new sendmail.cf and restarted sendmail.
I then created the file /etc/mail/authinfo:
AuthInfo:smtp.biz.rr.com "U:MyUserName" "P:MyPasswd" "M:PLAIN"
and then 'makemap hash /etc/mail/authinfo < /etc/mail/authinfo'
However sendmail seems to be sending out mail directly from the server
instead of relaying through smtp.biz.rr.com. I suspect this will
increase the chances of my emails getting blocked so I'd prefer to use
the relay. The tech weasel at Time Warner asked me how to spell
sendmail, so you can guess how far that call got me. Can anyone help me
diagnose or cure this problem?
Recommended set of test after the above (execute them as root):
1A) check $S smart host setting
echo '$S' | sendmail -bt
1B) check if smart host is honored
echo '3,0 j...@example.net' | sendmail -bt
2) send test message with tracking map lookups (authinfo lookups):
(echo 'subject: test'; echo) | sendmail -d60.5 -v j...@example.net
