You may wish to receive email notifications from your server for cron updates / scripts and such.
Within the Redhat environment covering Fedora / CentOS / Scientific Linux & RHEL the following method is advised:
(via root #) echo "root: firstname.lastname@example.org" >> /etc/aliases; newaliases;
As a user you can issue the following command to receive email notifications:
(via user $) echo "email@example.com" > .forward; chmod 644 .forward;
This will ensure that mails to root@localhost/user@localhost are redirected to your email address, this will assist with the security and management of your server.
