I can send email but can't receive email with Microsoft Exchange Server

I am trying to set up a Microsoft Exchange Server.  I have Windows 2003 server running.  I have pointed my mx record to my static ip.  I can send email, but I can't receive.

put your smtp domain name in http://www.checkdns.net/quickcheckdomainf.aspx and check if it reports any errors

Have you placed the MX record in a DNS server on the internet? You normally need to get your ISP or hosing company to do this so external mail can find your server.

I clicked on the link and did a DNS check.  It looks like I have a couple errors.  One says Error connecting to mail server stridekids.com port 25: connection refused.
Another says answer from dns1.earthlink.net: host smtp.stridekids.com not found and the last error says Some of the MX do not work properly.
Do I just contact earthlink?

if they manage your external DNS, yes.

make sure ISP is forwarding emails to your Static IP Router and then router is configured to send the mails to your exchange server.

I finally got this.  Thanks to all the good suggestions.  It was all my own stupidity.  I had the port forwarded on my router but I I overlooked forwarding the port on my modem.  Thank you all for the suggestions.
Glad your problem got solved.
