The condition we use is whether $interface_address is defined. If it's
undefined or if it's in 127/8, we consider the mail locally generated.
We actually define the condition the other way around:
# This condition is true if the message came from the outside world,
# ie was received over a non 127/8 interface.
FROM_REMOTE = and { {def:interface_address}\
{!match_ip{$interface_address}{127.0.0.0/8}}\
}
