Assuming 'domain.com', I'm hoping you don't actually call the box
'domain.com', but something like 'servername.domain.com'
If that is correct, call the new box 'newserver.domain.com' (the actual
name doesnt matter)..
Setup an MX record for 'newserver.domain.com', pointing at
'newserver.domain.com'. Use .forward file on the old box to send mail
for users that have moved to 'user@???' - this wont
change the To: header, so it should be transparent for users.
