Would their be any performance loss by having mailman send through the ip address of eth0 instead of the loopback?
Using eth0 instead of lo0 will result in real packets being generated and sent out the interface, and then coming back in. This could run foul of firewall rules, network stack configuration, DNS configuration issues, etc.... Using eth0 would also be less portable, and if you were to move the lists to another machine, you'd have to make more configuration changes to get them working again -- as opposed to putting a numeric 127.0.0.1 in your configuration instead.
Generally speaking, if you can help it, you want to use lo0.
Using eth0 instead won't necessarily hurt your performance on a medium or small-size list (it could hurt on a big list, depending on what other traffic the machine is doing), but it could potentially result in a lot of other problems that may be difficult to debug, etc....
