There are several issues. First off, by default RHEL doesn't allow root
access over the network--only on the console. To change that (and I do
NOT recommend this for security reasons), edit /etc/securetty. It
contains a list of the ttys that root IS allowed to log in on.
Second, NEVER, EVER, EVER use telnet! It is completely unsecure.
Usernames, passwords and ALL data is sent over the net in cleartext.
Use ssh instead. And even using ssh, never log in as root. Log in as a
normal user, then use "su -" to become root.
Third, the POP server (dovecot) by default doesn't allow access by users
with UIDs less than 500. Look at the /etc/dovecot.conf file for
details.
