The Problem the OP appears to fall into is that mail coming from outside
the mynetworks is being trapped to do a "local" DNS MX/A record.
It is probably pointing mail to the "example.com" as 127.0.0.1 (not
uncommon).
It points mail for the domain to the local server's FQDN. And that
translates to localhost because of entries in /etc/hosts.
Don't map your FQDN to 127.0.0.1 in your hosts file. Your FQDN should
resolve to your primary non-loopback IP address.
