Your ISP should have given you instruction how to connect netscape
mail to their SMTP server.
The same information is needed for sendmail to authenticate itself and
send mail out.
The authentication info commonly goes in /etc/mail/authinfo
In sendmail.mc I have lines like:
dnl # with authentication the following two lines
FEATURE(`authinfo',`hash -o /etc/mail/authinfo.db')dnl
and in /etc/mail/authinfo is the authentication info.
AuthInfo:isp.com "U:bigbob at isp.com" "P:MagicWord" "M:PLAIN"
AuthInfo: "U:bigbob at isp.com" "P:MagicWord" "M:PLAIN"
If you google search for /etc/mail/authinfo.db authinfo FEATURE sendmail
you will find more.
