	Are you sure that's true? You're supposed to be able to send mail to a
domain even if it's not connected directly to the 'net. Isn't that what MX
records are for? Beowulf.org has an MX record, so it's not like you don't
know where it's supposed to go.

	What if you have a mail-only domain? Why does it need an IP address?
