Kinda OT: "valid mail server"?

[Matt Nelson]

Well, I'm running at home with a /32 and a business network at work with
a /28.  I haven't tried yet but I doubt SWBell is going to allow me to
manage my own reverse DNS.  Anyone have any suggestions?  So far its
only redhat's mail server that is doing this, and although I'm deploying
their product, I can't subscribe to any of the user lists they run. :-(
