Well, as it has been said, mailx is not an MTA, and it takes an MTA to
transfer mail (even locally, because it crosses privilege boundaries).
In the "old days", /bin/mail was setuid and could directly write
/var/mail, but there were security issues with that and it is no longer
supported (it also caused confusion when you actually had a local MTA
configured to smart-host to a remote server).

If you want to handle mail in any fashion beyond using a client that
sends/receives via network protocols (IMAP/POP3 and SMTP to a remote
server, like mutt or Thunderbird), install an MTA.  IIRC, at least
Postfix and Sendmail will work for local mail handling (and not
listening on the network) in a default install, so "yum install <your
preferred MTA>" and you should be set.
