Sure, but when the destination IP address is listed in inet_interfaces,
the connection is not even made and a loop is detected. Hostname tweaks
don't help in this case, the idea is to not forward to your own port
25, where "your own" means an IP address that is listed in instance's
"inet_interfaces".
