Unable to respond to email

On our SBS 2003 server I have set up a 2nd domain for email delivery.

Only a few people in the organization need both the original email (@domain1) and the new email (@domain2) addresses.

I have verified that sending and receiving email from external sources to these addresses works correctly.

For those employees that only need the new address (@domain2), I simply added the new address to the "E-Mail Addresses" tab in ADUC and made it their primary SMTP account. Now, when they send email from Outlook, it uses the @domain2 domain by default. Great!

The only problem I have now is that when these people send emails to recipients in the other domain (to @domain1) users, they receive the email. But if someone from @domain1 tries to email a user @domain2, the recipient never receives the email.

It hasn't been long enough to receive an NDR, so I'm not sure what the error will be exactly. Any idea what's going on?

The Exchange queue shows the test messages in the Local Delivery queue...just waiting.

Just to confirm as you don't state it - have you added the relevent recipient policy in Exchange?

I have @domain2.com listed in the "E-Mail Addresses" tab of the Default Policy. I believe I have this set correctly since external email is delivered properly.

Both domains that are being accepted into the Exchange should have a recipient policy, but I was just trying to establish whether one existed

Can run a message tracking on the Exchange 2003 box to trace an email sent from domain 1 user to a domain 2 user and let us know what output you get

Thanks

Thanks for the input DLeaver. I have no idea what happened, but over the weekend, we're suddenly able to send mail to this domain now. Sometimes these delays are a mystery to me in Exchange - but it works!
