Sendmail for Solaris 2.6

How do I configure send mail to send mail to internet mail accounts. The system is on a network which has an internet net router configured.

If you can get to the internet, then it should work.

Is sendmail running? (ps -ef|grep mail)
What version of sendmail? (/usr/lib/sendmail -d0.1 -bt < /dev/null)
What do you have on the lines in the sendmail.cf file for DH, DR, and DS? (sendmail.cf should be in either /etc or /etc/mail)

This is probably not what you are looking for, but I shall
reply anyway. Have you considered qmail instead of
sendmail. I find it a lot simpler to configure and
administer.
