sendmail - Unable to send mail to external emails

I have sendmail running on solaris 9. I am able to use sendmail to send mail
to my internal email but I could not send mail to my.yahoo.com or comcast.net
. I check with network admin guy and he says there is no firewall restriction
on my server I could do anything with it. Is there any configuration I need
to look into? Below is the output when I run send mail, it shows relaying
denied. Thanks in advance, David

/usr/lib/sendmail -v itbookdot@yahoo.com < /etc/nodename
