I cannot send email from a 2010 mailbox to a 2003 mailbox, it queues on the hub transport server. when i check the queue i get a "451 4.4.4 DBS Query Failed. The error was: SMTPSEND.DNS.NonExistentDomain; nonexistent domain"

what domain can it not find?

OWA is working and i can send from a 2003 mailbox to a 2010 mailbox just not vice versa. I have only moved my mailbox for testing purposes so I can get this working before migrating any other mailboxes to 2010.

OWA also correctly redirect user to 2003/2010 depending on where mailbox is hosted.

--------> Original Setup
(One Exchange Organization)
DOMAIN A:
A-EXCHANGE --> Backend 2003 Exchange Server (SMTP Mail is send here from ISP)
DOMAIN B:
B-EXCHANGE --> Backend 2003 Exchange Server
B-OWA --> Frontend 2003 Exchange Server
---> Setup Now
DOMAIN A:
A-EXCHANGE --> Backend 2003 Exchange Server (SMTP Mail is send here from ISP)
A-2010-EXCHANGE --> Client Access, Mailbox, Hub Transport | 2010 Exchange Server
DOMAIN B:
B-EXCHANGE --> Backend 2003 Exchange Server
B-OWA --> Frontend 2003 Exchange Server
B-2010-EXCHANGE --> Client Access, Mailbox | 2010 Exchange Server
B-2010-OWA --> Client Access | 2010 Exchange Server

Create a new test user residing on the Exchange 2010 server and see if it can send mail to an exchange 2003 mailbox. Since mail is flowing from 2003 to 2010, it means a routing group connector exists. Can you run GET-ROUTINGGROUPCONNECTOR | FL command from the management shell and post the output please?

New test user exhibits exactly the same behaviour, the message queues with the same error as above.

Note i've edited the output to reflect what I have called the servers in the post above, I was extremely careful, obviously a mistake is possible.

Does email to the internet work? When sending to E2K3, are you selecting the user from the address list or typing in the address (please try both methods)?

Email to internet to and from works from 03 and 10.

Interestingly I sent some messages last night as a test at around 00:30 they finally went through around 11:20 this morning?????? I then sent a test email immediately afterwards that went through straight away.?

I then sent another test email a few minutes ago 12:50, its queued with the DNS error?

I had a similar issue last night with my in-process 2003 to 2010 migration. I had read that the SMTP ports on both 2003 and 2010 have to be set to port 25, however I totally forgot I had changed the receive connector on 2010 to port 24 because I had XWall (a 3rd party spam/junk filter) running on port 25.

So I guess make sure your 2003 Default Virtual SMTP thing is set to '25', as-well-as the Receive Connector on 2010 *shrug*
