Actually I thought about this myself lately... the reason you'd maybe want to change your ip is if your machine is on a multi-homed natted box and recieving mail from an internal LAN. Then it will report the internal address on the header, unless you do some more natting (madness in my eyes, since multiple NATS can be dodgy).
I don't want MR.Hacker to know the ip address of my internal machines ... do I .
Just change the macro in the sendmail.cf... oh and buy the Bat book just for extreme measure

wakeonlan
WAKEONLAN(8) BSD System Manager's Manual WAKEONLAN(8)
NAME
wakeonlan -- send Wake on LAN frames to hosts on a local Ethernet network
SYNOPSIS
wakeonlan [interface] lladdr [lladdr ...]
DESCRIPTION
The wakeonlan program is used to send Wake on LAN (WoL) frames over a local Ethernet network to one or more hosts using their link layer
(hardware) addresses. WoL functionality is generally enabled in a machine's BIOS and can be used to power on machines from a remote system
without having physical access to them.
interface is an Ethernet interface of the local machine and is used to send the Wake on LAN frames over it. If there is only one Ethernet
device available that is up and running, then the interface argument can be omitted. lladdr is the link layer address of the remote machine.
This can be specified as the actual hardware address (six hexadecimal numbers separated by colons) or as a hostname entry in /etc/ethers.
wakeonlan accepts multiple lladdr addresses. Link layer addresses can be determined and set using ifconfig(8).
FILES
/etc/ethers Ethernet host name data base.
SEE ALSO
ethers(5), ifconfig(8)
