DNS: A record for domain?

Question

Trying to configure BIND in Snow Leopard Server so I can migrate current DNS to an XServe. My goal is to be able to use Server Admin for as much as possible, but I know this won't be entirely possible in my setup (wildcards, bizarre reverse delegation limit my options here). I've used generic names here on purpose, but yes, I do know what I am doing.
Currently, I'm trying to create an A record for a domain so that I users will hit my website whether they enter domain.com or www.domain.com. I have the following entry to my domain in SA:
+domain.com. Machine 1.2.3.4+
I verified that this entry was correct in the zone file itself. Indeed, I found the following entry in the appropriate zone file:
+domain.com. IN A 1.2.3.4+
However, when I attempt to query the server using dig, I do not get an answer:
dig a domain.com @server.domain.com
; <<>> DiG 9.6.0-APPLE-P2 <<>> a domain.com @server.domain.com
;; global options: +cmd
;; Got answer:

What am I missing here?

Be aware that this is not a production server yet, and I acknowledge that this isn't fully kosher yet. I am just testing the config to see if it will work.
Server is 206.123.100.18. Zone is a3dtech.com. Zone file:
;GUID=4EAE5E10-15F4-457B-8CAC-D9702FB1E186
;selfResolvingHostname=0
$TTL 10800
