email from secondary domain name not working following re-run of internet connection wizard in SBS2003

I have changed the IP addressing on our SBS2003 server, modified the DHCP scope and the router firewall rules and everything is working ok except for one thing. We have 2 email domains set up on the server and the default on still works but we can no longer send emails from the second domain. The only thing I can think of that might caused this is that I had to re-run the internet connection wizard to allow internet access after changing the IP but I did set it to leave the email configuration as was.

Any ideas??

When running the internet connection wizard you need to run the email section too. I will reset all your smtp connectors. (including the second domain)
If not reset the second doamin manually (only if the wizard doesn't do it automatically)
Hope that helps,

My mistake, second email account was POP3 set up in the outlook client using the sbs server as the mail server and the guy that set it up set the pop/smtp mail server address as the IP so all I needed to do was change that and modify the allowed IP range in the relay section of the default smtp server.
