How to configure for mail command
 

I have a RH 9.
I want to use the mail command to send emails to me
e.g.
Do i need to provide a smtp server ip in my RH 9 for mail command?

If yes, how to do it ?

Which is so obsolete it's fossilized.

ls | mail -s "Sending email" khaos83_2000@linuxquestion.org
... send a directory list to yourself as a test. I suppose. What happens when you try?

cat /usr/share/common-licenses/GPL-3 | mail -s Testing khaos83_2000@linuxquestions.org


I don't think you'll get very far with mail, have you tried sendmail?
