Hosting email on Exchange 2000 for a 2003 domain in the forest

We currently have two Windows 2000 domain trees in our 2000 forest and an
Exchange 2000 organization hosts email for both domains. We are getting
ready to add a third domain tree that will be running Server 2003. My
question is "can Exchange 2000 host mail for the 2003 domain, and if so, will
the Exchange 2000 domain prep work on the 2003 domain?"

Thanks in advance.

Yes, the 2000 prep will be ok on the 2003 domain. Yes you can host the
domain from the new tree.
