Cisco WAN :: 5505 Routing Server Initiated Traffic From DMZ

I have setup an ASA 5505 w/ Security Plus with three subnets. The subnets are as follows:

VLANSubnetWAN 10.0.0.80/29LAN192.168.1.0/24DMZ172.30.200.0/24 ]

The ASA is the gateway router at .1 for the LAN and DMZ networks. On the WAN network, the ASA occupies .85 and uses .86 as it's gateway to the Internet. Clients on the LAN are able to access the Internet without any troubles. I have a static NAT setup to map the DMZ server's 172.30.200.81 address to 10.0.0.81. I also have a general NAT that should allow other servers on that network to access the internet, but no machine at all on that network can route outside of 172.30.200.0/24. I used the packet tracer and had it trace traffic coming from the DMZ network to the Internet, and it did not show me any conflicts with any of the access lists or anything else. However, no matter what I do, I cannot initiate traffic from the DMZ and have it go out to the Internet successfully.I attempted to follow the directions in the article PIX/ASA 7.x and above: Mail (SMTP) Server Access on the DMZ Configuration Example; but I have obviously missed something, done something wrong, or perhaps the example assumes something about my configuration that I have not done. See the attached config file that I have scrubbed. I have removed  VPN configuration information and other unnecessary parts of the  config file to make it easier to read.
