Thanks Marshall, but I got some strange result: 1) When I changed the "Dj$w.Foo.COM" to "Djihe.com" I got the following error 3:06:05> minh.nguyen@xxxxxxxxxx User unknown /root/dead.letter... Saved message in /root/dead.letter I did it using the following command: mail -s "testing" minh.nguyen@xxxxxxx < /etc/hosts 2) When I changed the "Dj$w.Foo.COM" to "Dj$domain.com" the email goes through, but it showed up with a letter missing in the domain name: "root@xxxxxx" instead of "root@xxxxxxx" Any ideas?

That should do it.
