I have set up a PC at work with RH 9 , web server, etc. I am attempting to figure out how sendmail works. When I use "mail" at the prompt I am getting this error im my log:
Action: failed
Status: 5.5.4
Diagnostic-Code: SMTP; 553 5.5.4 <root@localhost.localdomain>... Real domain name required for sender address

Can any one direct me to some EASY to understand tutorials and/or resources to figure out how to configure sendmail? I have been to their site and will continue to look their, but I thought I would check here also. Thank you.

With the help of someone at work I was able to figure out the problem. In network setup I changed localhost.localdomain to the name of my server and then I also had to add the IP address of our mail server along with a name to the hosts file. Hope this helps anyone else who may have this problem.
