I don't know about your entire reverse, but your IP of your mail server
resolves back just fine. Shouldn't be any problems. Is your mail server
set up with the right domain name? When your mail server issues a HELO,
it's going to need to know that it's name is nextnet.com. If it thinks
it's mail.nextnet.com, because you've set that in the mail server settings,
but the IP number of the machine resolves back to nextnet.com, it might
annoy some other mail servers. Maybe even enough to generate and error and
cause a bounce, or misrouted (or black holed) e-mail. You never can be too
sure.
