Single Exchange 2003 Server in Forest

I am about to introduce an Exchange 2003 server in to our Forest which is made up of mostly 2003 servers, a few 2000 left.  I have the top level domain of .local and several child domains.  I want the Exchange server to serve all.  Should I add the Exchange server to the top lever domain?  Should it be a domain controller?  Will I be able to create mailboxes for existing user accounts in the child domains?

Thanks in advance

It really doesn't matter where you put it since it will be able to service all your accounts in all your domains.  Depending on the amount of users I would place it on a seperate server.

just have the MX record for the exchange server in all your respective DNS zones ? make sure that SMTP traffice is allowed, and route between your subnets, LANs, WANs etc etc.

Exchange would be best placed on another server and shouldnt be on a Domain controller - In an ideal world. (It will work on one)
Make sure MX records are setup correcly as SeanUK77 suggests
