forward emails from the root user account to the admin user account centos

Sometimes we need to forward an email received by some user to the other user. Say If we have an admin user account in our centos machine then we need to forward the emails from the root user account to the admin user account for that we need to edit the file /etc/aliases

[root@server105 ~]# vi /etc/aliases

At the bottom of the file you can see the following

# Person who should get root's mail

#root: marc

Just add

root username

under that and it will work fine

for me it is

root joji

Thank you
