The "relaying denied" message comes from sendmail, and not from the DNS
(which seems to be where you're looking). The mail is arriving at
mail.y.z, but because sendmail doesn't believe itself to be the MX for
domain y.z and because domain y.z isn't an allowed relay as defined by
sendmail.cf (silly, yes) it bounces the mail with the "relaying denied" error.
You need to configure sendmail.
Sendmail prefers that you use the M4 method of sendmail configuration,
however, in RedHat 6.x the easiest way is to use linuxconf and set it to be
the MX for domain y.z. Sendmail does not recommend linuxconf use to
configure sendmail because it doesn't use the M4 method (it just rewrites
sendmail.cf manually), however, it works and you won't likely have any
trouble.
