Thank you Wietse for the answer, I have one last question since I never have
modified the master.cf does the following look correct:
# Postfix master process configuration file. For details on the format
# of the file, see the master(5) manual page (command: "man 5 master").
#
# ==========================================================================
# service type private unpriv chroot wakeup maxproc command + args
# (yes) (yes) (yes) (never) (100)

lmtp unix - - n - - lmtp

I am not sure if I should have two relay directives in my master.cf or just
edit the fallback_relay to smtp_fallback_relay.
Thanks
