Question : How do I get email to my exchange 2007 server?

The install of exchange server 2007 is complete. I have added the needed domain under accepted domains. We will call this mysample45.com

My IP address is 123.123.123.123

I know I need to forward the MX / A records to my server.. I know where to do this under the control panel from my domain supplier aplus.net ----

What do I need to do now?

Answer : How do I get email to my exchange 2007 server?

you're almost there

forward port 25 tcp in your router, to the inside ip of your mail server...

and of course wait 24-48 hours for dns propegation to happen - it's not instant.

you can test it by telneting to your ip address from an outside connection, at port 25:
telnet 123.123.123.123 25

if you get a line that starts with 220, you're good
