First of all, if the above is the zone file for gregbates.com, you need A
records for listserve and for server[23]. You might also want to make the
priority 10 MX record point directly to gregbates.com instead of going
through the mail alias. - In order to add computer2 to the domain, add an
A record for it as well.

As for reverse lookups, how you would make them work depends on the kind
of network you have. If you have at least a /24, your ISP or your IP
registry should delegate that network to you, and you would set up a
reverse zone in the classic fashion. If, OTOH, you have a /25 or less,
you'd need to work with your ISP to set up the kludge described in RFC
2317 - or you could let your ISP handle reverse DNS for you completely.

You can name the zone files almost at your discretion as long as your
named.boot correctly points to them.

Btw., IIRC BIND 4.9.5 has security vulnerabilities, so you might want to
upgrade to a more current version.
