4sight? as in, foresight? You think using your email address as a publically visible username is foresight? You'll just get spammed.
Again, another lack of foresight is to use fedora 14 as a server. It's old software, and NOT a server. you should NOT use fedora as a server. Use CentOS or RHEL as a direct alternative. Not Fedora.
Finally, there is no definition of what an "email server" is. smtp? pop? imap? webmail? Most often this means SMTP, and that would be postfix by default on the Redhat family. This will already be installed on your system, there is nothing to "send" you. Just read some documentation for it.
