Question Setting up BIND with dynamic IP
I'm a UNIX newbie, so I know I'll be making foolish errors here...

I'm trying to set up my Mac OS X 10.2 server to serve my domain name. [Caphector.com, currently hosted by Hostsave.com] I've got Apache running reasonably well [It needs to be restarted after a system restart or it gives a 404], and I know Sendmail is up and running...

Now, I seem to need to get BIND running for the domain name, and it seems to need a static IP for the BINDing but I've got a dynamic IP for my local server so I'm planning to use Afraid.org for my DNS server.

However, I've been seeing some people saying that I need to run BIND as a local DNS server and/or that I need to set my machine as the primary DNS for the domain name.

Which leads to the second problem: Mail sent via Sendmail to/from my server doesn't get delivered. Mailq is empty, and I don't get any "your message wasn't delivered" messages. I can send to the server because caphector.no-ip.info is redirected to it. At least, I think I can....

So, how/why do I setup BIND, and what's wrong with Sendmail?

dnsextd

dnsextd(8)						    BSD System Manager's Manual 						dnsextd(8)

NAME

     dnsextd -- BIND Extension Daemon

SYNOPSIS

     dnsextd

DESCRIPTION

     dnsextd is a daemon invoked at boot time, running alongside BIND 9, to implement two EDNS0 extensions to the standard DNS protocol.

     dnsextd allows clients to perform DNS Updates with an attached lease lifetime, so that if the client crashes or is disconnected from the net-
     work, its address records will be automatically deleted after the lease expires.

     dnsextd allows clients to perform long-lived queries. Instead of rapidly polling the server to discover when information changes, long-lived
     queries enable a client to indicate its interest in some set of data, and then be notified asynchronously by the server whenever any of that
     data changes.

     dnsextd has no user-specifiable command-line argument, and users should not run dnsextd manually.

SEE ALSO

     mDNS(1) mDNSResponder(8)

     For information on Dynamic DNS Update, see RFC 2136 "Dynamic Updates in the Domain Name System (DNS UPDATE)"

     For information on Dynamic DNS Update Leases, see http://files.dns-sd.org/draft-dns-update-leases.txt

     For information on Long-Lived Queries, see http://files.dns-sd.org/draft-dns-llq.txt

BUGS

     dnsextd bugs are tracked in Apple Radar component "mDNSResponder".

HISTORY

     The dnsextd daemon first appeared in Mac OS X 10.4 (Tiger).
