Dave - if you already have sendmail working it is very easy to turn off
relaying.
1. Stop sendmail "service sendmail stop"
2. edit "/etc/mail/sendmail.mc" (make a backup copy first!!!)
3. change or remove the options allowing relaying
(if you need help here, send me a copy of your sendmail.mc
AFTER removing any security risk info !! or post it.)
4. regenerate your sendmail.cf file by issuing:
"m4 /etc/mail/sendmail.mc > /etc/sendmail.cf"
5. service sendmail start
