Dear Noel, Thanks for your reply.
Does it mean on my new Exchange 2010 server, I need to add "@new.example.com" email address for each recipient? For example, If I send email to p...@example.com. After postfix process, it rewrite the email address p...@new.example.com and delivery to our new Exchange server. It is possible to do it with rewrite the recipient email address?
