Port 25 problem Trying to enable exchange

I am enabling exchange 2007 tomorrow morning and I have a problem. I am going through my test list to ensure everything is correct and I cannot connect (from the outside) to port 25. I have opened it up on the Router and point it to the server and I have added a firewall rule to allow it.
If I attempt to ping it I get:

C:\Users\Don>telnet 1.2.3.4 25
Connecting To 1.2.3.4...Could not open connection to the host, on port 25
: Connect failed

I should be able to connect in on port 25 shouldn't I?

just as long as it is not configured for ssl..

Do you need to port-forward the public IP?

I have not yet changed the MX record. I want to test that everything is going to work easily and quickly as i have other issues that I will need to address.
I did verify from the ISP that there are no port restrictions in or out on the IP address. I am pinging by address, not name just to be sure I reach the correct server.
Where would it configured for SSL?

I did purchase a cert from Go Daddy. How do I check if I added Port 25 for SSL? Is this a default? Will this make it work without any further concerns?

My OS is SBS 2008 if that matters.

There is nothing to do with SSL. Probably you have to configure your connector. Start with http://technet.microsoft.com/en-us/library/bb125128.aspx for overview then follow links at the bottom.

your cert should have your domain registered, if that is not changing, neither will it..

Have you gone into your Virtual SMTP adaptor and checked if SSL is enabled?

Check the IPv4 ranges the server is set to accept connection from. I can provide more detail tomorrow when I am back in the office.

I assume you can telnet to port 25, and that you have tested it, on your internal network?

If so, then the only thing that can prevent you telnetting externally would be an incorrect firewall setting, or IP restrictions set in Exchange System Manager. What firewall are you using?

Do you have a fixed external IP?
