Unfortunately, people behind firewalls can't use $interface_address. At
work I have this problem so I have to put my ip there. I've also locked out
IPs that aren't from the sender at work (excluding the 10/8, 172.0/12, and
192.168/16 networks which I've yet to see). This does catch some, but not
enough to bother coding it.
