Exchange server can send mail but not receive

I installed exchange server this week end.  I can send mail but not receive email.  I think my DNS is ok but not sure.  I am thinking it's probably a relay configuration issue.  I'm looking for ideas.  

C:\>nslookup
Default Server:  joeker.org
Address:  192.168.1.20

> server 66.58.23.34
Default Server:  node-423a1722.mdw.onnet.us.uu.net
Address:  66.58.23.34

> set q=mx
> joeker.org
Server:  node-423a1722.mdw.onnet.us.uu.net
Address:  66.58.23.34

joeker.org      MX preference = 10, mail exchanger = 192.168.1.20
joeker.org      MX preference = 10, mail exchanger = 66.58.23.34

If you have a internet domain, contact your ISP to forward all incoming mail to your IP, next setup security against spammail in "System manager / Servers / Servername / Protocols / SMTP / Default SMTP Virtual Server
Right click on Default SMTP Virtual Server and select Properties, next select Access, now click on Connection Select "Only the list below" and add your local subnet in it i.e. 192.168.1.0/255.255.255.0 AND ADD the mail server of your ISP.. (call them and ask what IP they use for BSMTP)

Now click OK and click on Relay, again select "Only the list below" and add ONLY your local subnet and click OK.. that should do the trick.

I'm now running a test on your IP if it allows spam using
http://fabel.dk/relay/test/index.epl?ip=66.58.23.34&send=Check

I'll keep you informed on the relult.

This means.. do as fast as you can what i said earlyer..

Right click on Default SMTP Virtual Server and select Properties, next select Access, now click on Connection Select "Only the list below" and add your local subnet in it i.e. 192.168.1.0/255.255.255.0 AND ADD the mail server of your ISP.. (call them and ask what IP they use for BSMTP)

Now click OK and click on Relay, again select "Only the list below" and add ONLY your local subnet and click OK.. that should do the trick.
 
YOU ARE A OPEN HOST FOR ALL OF THE INTERNET!!!

BTW, i'm assuming you have a fully qualified domian with BSMTP.. if your domain has a catch all POP3 account.. then it needs some extra configuration.. but DO the things i said earlyer...

On the default SMTP server I already had "Only the list below" selected.  I guess it was the Connector address space setting "allow messages to be relayed to these domains" i had check that left me OPEN FOR SPAM.  hehehe

anyway, now the relay test shows closed

But the main issue of not receiving email still exists.  I guess I need to contact my ISP as you said.  I didn't realize they need to forward to my IP.  Is this common?  I didn't find it in any of the technet pages.

What is BSMTP?  How do I know if my domain names have BSMTP or 'catch all POP3 accounts'???

Thank you for the help so far.
I am running my own DNS server.  Why would I need to invole my ISP?  
I bought the domain name, joeker.org, and I setup my DNS server to point to my IP and it works on the internet.  I've been hosting sites for a couple years, but I am new to DNS and exchange server.  Until now I always used free DNS services and email.  I don't understand why I can't receive mail.

I found the problem.  I had 2 MX records in DNS.  One was using my local IP address and the other the WAN IP.  I deleted the MX record with the local IP and all is well.  Except I think I already got blacklisted due to my poor relay settings originally.
I didn't need to contact or even invole my ISP(thank God).

And thank you Goldwing.
You get the points because you made me aware of the relay issue which would only have gotten worse if you hadn't pointed that out.  I appreciate it.
