You're not doing port forwarding, so X11 traffic from z comes straight
back to x. X looks at the source address (z) and drops it since z is
not a permitted host. Add z to the list of permitted hosts.

Did you export the DISPLAY variable to point to the machine running the X
server?

$ export DISPLAY=mymachine.whatever.com:0.0

Rather than using telnet for this, use ssh. Not only will your session be
encrypted to make it more secure, but ssh can automatically enable
X-forwarding:

ssh -X remote.machine.com

[remote.machine.com]$ xterm&
