Exchange 2010 Server not sending emails

It worked for a short time, and then for some reason it just stopped.  I can't figure out why either.  I'm obviously missing something and it's begging to irritate me.

So here is how everything is setup.

The public IP of the server is 99.28.107.226

There is just one server, Windows 2008 R2 with Exchange 2010.
A send connector has been setup to allow all smtp traffic.

I am going to be allowing multple domains to send emails, right now I just have a few setup just to test things out.

The server runs as a domain server, web server, and exchange server.

This system is setup at home, for testing purposes, so that's why there is only one server.  I can receive emails just fine.

On my registrar I have DNS setup like this:

A records

www.450p.com 86400 IN A 99.28.107.226  
test.450p.com 86400 IN A 99.28.107.226  
ftp.450p.com 86400 IN A 99.28.107.226  
mail.450p.com 86400 IN A 99.28.107.226  
*.450p.com 86400 IN A 99.28.107.226  
450p.com 86400 IN A 99.28.107.226  

MX Record

450p.com   IN MX 10 99.28.107.226

The main domain name of the server in question is ghp.lcl
The user accounts have email accounts setup for 450p.com and 450p.com is an allowed domain in exchange.

On the DNS side of my server I have the following:

(same as parent folder)  Start of Authority (SOA) [17], ghp-server.ghp.lcl, hostmaster.ghp.lcl
(same as parent folder) Name Server (NS)  ghp-server.ghp.lcl
ftp  Host(A)  192.168.1.2
mail Host(A) 192.168.1.2
test Host(A) 192.168.1.2
www Host(A) 192.168.1.2
(same as parent folder) Host (A) 99.28.107.226

The main domain of the server has the DNS records of:

(same as parent folder)  Start of Authority (SOA) [35], ghp-server.ghp.lcl, hostmaster.ghp.lcl
(same as parent folder) Name Server (NS)  ghp-server.ghp.lcl
(same as parent folder) Host (A) 192.168.1.2
ghp-server Host (A) 192.168.1.2
(same as parent folder) Host (A) 99.28.107.226

Reverse Lookup Zones is setup as:

1.168.192.in-addr.arpa

(same as parent folder) Start of Authority (SOA)  [10], ghp-server.ghp.lcl., hostmaster.ghp.lcl.
(same as parrent folder) Name Server (NS) ghp-server.ghp.lcl.
192.168.1.2 Pointer (PTR) mail.450p.com
192.168.1.2 Pointer (PTR) ghp-server.ghp.lcl

I also have another domain out there that I was doing a test  with called mail.ghpstudios.com that is also set to 99.28.107.206 (external DNS only).  I don't think this would cause any issues, but maybe I'm wrong in that regard.  

What I would like is to have the emails that go out say they are from the domain they are being sent from such as 450p.com, not ghp.lcl (which is only an internal domain).

Any ideas what I might be doing wrong here.  The only versions of exchange I have worked with before are Exchange 2000, and 2003.  2010 is very different and stumping me on this issue.
