Never done it that way personally; the machine this message is being
sent through, (our mailserver), has several NIC's, each with several IP
addresses. They are aliased using the same netmask. For example, I have
one NIC, (on internal LAN), aliasing 16IP addresses in the 10.0.0.255
network, all using 255.255.255.0 as their netmask. This may be
incorrect, but it works?
