Cannot send to external addresse, but can receive external & send & receive internal
We replaced our primary DC running Server 2003 and the following error popped up on our existing Exchange Server 2003.
Users can send and receive to any internal address. They can also RECEIVE mail from external addresses. However, no one to SEND e-mail to EXTERNAL addresses. Any suggestions.
Everything has been working fine for 2+ years until we replaced our Primary DC. Thanks.

Yes the old DC was the only DNS server. I removed and reinstalled the DNS service on the DC because I could not connect to the internet, but after the reinstall and adding forwarders DNS is working.

I have not changed any settings on my Exchange Server prior to and after the replacement of the DC.
have you tried to nslookup an address from the exchange server?
If it cant see the outside 'DNS' world, it will never resolve to send.
So maybe your new DNS server is a root server itself and not forwarding properly?
Is the firewall blocking port 53?

The firewall configuration has not changed, and it worked fine before the introduction of the new DC.
I can connect to webpages on the EXchange server and can telnet to my ISP local mail server to send test e-mail. However, I cannot telnet to any other mail server.

Yes I am using the DC as the DNS. And I am using domain names. The only domain name I can connect to on port 25 is mail.alltel.net (MY ISP mail server).
And what about telnet to the ip address of a known email server?
Or was the DNS forwarder in exchange, using the DC for resolution?
