Email works by mail servers relaying mail to each other until it gets
to a server that (believes) it can deliver it locally. There is either
something wrong with the MX records in your domain, or your Postfix
server is actually set to relay mail to the DNS, for some reason.
Check your postfix config for settings related to relaying or
smarthosts, and check your DNS config to see if all your MX records
are correct.
