AD DNS Name and Internet Domain Name the same

I have upgraded our exchange 5.5 server to 2000, now I have an issue with sending and recieving external emails.
Let me give you the layout.  Have AD domain name of  Have Internet domain registered as as well.
When users send users out or people send to people internally,  the mail does not go.  There are no errors.  
The smtp virtual server queue does not show any mail queued up.

Now I have another internet domain name of  I added that to a users email addresses and made it the
default return address.  Now users can send and receive emails.  They can get emails either under the .biz address or the .com address as long as .biz is the default return address.

While this works, we have used .com all this time and do not want to switch to the .biz, it is only for emergency.
Does anyone know as to why and how this can corrected?

Check the recipient policy, see if is listed, and check to see that it's the primary address. then check to see if you can rebuild your RUS successfully, without errors. Did you have any Fax software on the 5.5 server?

ID: 10877135 is listed.  If I make it the default, mail doesn't go thru.  I did not have any errors with rebuilding rus and mail still will not pass thru.  No I did not have fax software installed.

When you make it default, did you check the box to make the Exchange org responsible for all email? Second, does the email stay in the outbox?

Sorry it took so long to get back to you.  Was away yesterday.  Yes it is checked to make it responsible.  And no the email doesn't stay in the outbox.  It loks like it goes, but the smtp queue never shows it in there.

Does it matter that the internal and external domain names are the same?
The thing that tells me that maybe it doesn't matter is that as long as .biz is the default, I can get mail received on the .com address.
Could there be something corrupt in AD?

honestly, sounds like DNS. If you cannot find it stuck in the queues or the categorizer, then I'd guess DNS or yu have a corrupted metabase, which can be fixed with a long but simplistic removal and reinstall of SMTP. Do you have message tracking enabled?

I went back into dns and reconfigured the settings for the email server even though they were there.
I have been testing only my email account by removing the .biz address and sending a message from my hotmail account.  So far and it seems to be working.
Next test is to start removing the .biz from more users and see if they have a problem.

Thanks for your help.  If I run into more issues I will let you know.
