My SBS 2003 server has stopped relaying email to certian domains like hotmail or yahoo.  

Here is an example of the error msg I get:
Your message did not reach some or all of the intended recipients.

Subject: Test Email from SBS2003 server
Sent: 10/30/2006 8:42 AM

The following recipient(s) could not be reached:

  zachtop@hotmail.com on 10/30/2006 8:42 AM
  You do not have permission to send to this recipient. For assistance, contact your system administrator.
  <dhsystems.net #5.7.1 smtp;550 5.7.1 Unable to relay for zachtop@hotmail.com>

I am using a connector to send all email via an external server, this was working just fine until today.  If I login directly to the external server I am able to send email to these domains just fine.

How do I go about fixing this problem?

You don't have a reverse lookup record configured for your IP Address.  This would be done through RoadRunner.  Many major ISPs now block mail servers that don't have a reverse lookup.  You can review your mail server's settings at http://www.mxtoolbox.com

I would also note that you have configured your DNS Zone file with GoDaddy to point www at your SBS's IP.  Generally you don't want to have a publically available web site hosted on your SBS.  Which, as of now, has port 80 open as well... another thing that's not good to do.  Port 80 can be closed by rerunning the Configure Email and Internet Connection Wizard (CEICW -- which is linked as Connect to the Internet in the Server Management Console > Internet and Email)

A visual how-to is here:  http://sbsurl.com/ceicw and a full networking overview for SBS is at http://sbsurl.com/msicw

I found the problem... Since the IP address of my local server changed the config of my relay server had to be updated.  If was a simple problem.
