I appreciate if you respond to my question.
I have an email server hosted externally now i use SMTP,PoP3 to send and recieve email but i would like to keep the extrenal one and setup an Exchange server 2007 in my local network to use the same domain name sending and recieving email, the aim of this setup is to provide a centralize email storage for daily backup purpose. It wuold be nice if "external and Internal ones" provide redandunce if external fails then i internal should work and vice versa.
