Some Messages (Not all) get stuck in my SMTP Queue

I have a webserver sitting in my dmz and it hosts a couple of webservices in particular some online calenders. The calenders allow people to submit new events to add to the calender, and then when they are approved the submitter is sent an email notifying them that their event was approved. The webservice first sends out an email to a calender administrator within my department to say that they have a new message to approve.

Ok, here is the problem. The emails that should go to the submitter (outside our domain) go out just fine, but emails that should go to our administrators (inside the domain) get stuck in the queue.

For example:
joebob@yahoo.com posts a new event to the calender. The administrator of the calender is bill@winnebagoschools.org.
Bill's email get stuck in the queue, but joebob's email gets sent correctly.

Here is what I have done thus far:
- I have tried creating a remote domain that points to the IP address of my internal network's mail server.
- I have under the delivery tab and advance options put the IP address of my internal network's mail server.
- I have tried putting a email directly in the pickup folder.

Someone save me .... PLEASE!

Thanks
Ben

Can the SMTP server you are using do an MX lookup on "winnebagoschools.org"
and then telnet to the address? (cmd; telnet hostname 25) Can the web
server "get" to the SMTP server? Does it have permission by the SMTP server
to send mail?
