Friends don't let friends use Sendmail. There are other (read better) alternatives to Sendmail, and I would suggest qmail.
http://www.qmail.org
I would argue that friends don't let friends get bullied and beaten on the qmail list and that friends don't force friends to patch and recompile just to prove they have hair on their chest. Qmail itself, as well as the mailing lists that relate to it, are hostile, pure and simple. A total novice just asked for a GUI to help him do basic Sendmail configuration (a 15-second task when one knows what one is doing, 10 minutes or so for the novice following instructions), and you offer him qmail???
I must say I find this sadistic.
To the OP: Please post what version of Red Hat you are running, and a little about your environment and the tasks you want the server to carry out. Also, I do suggest that you quickly download and install Webmin, then follow the instructions on the Webmin site on activating SSL so that your access to it is secure and encrypted. While you do that, we'll get your sendmail configuration squared away and running fine in a few minutes.
By the way, many people have argued that sendmail is great because it's been around forever. Others argue that its age (and thus by extension its design) are old-fashioned and that there are better packages available to replace it. Feel free to explore this debate, just be aware that it's almost religiously blind to reason... most people love one, hate all others. In particular, though, I suggest that you do evaluate postfix very closely; since Red Hat provides you the option to use sendmail or postfix easily and in a plug-in fashion, postfix is likely to be the alternative MTA which is easiest to use in place of Sendmail for a novice on Red Hat Linux.
