what's the difference between Default SMTP virtual server and smtp connector? by default with a fresh installed exchange 2003, I don't see nothing under connector. But i was still able to send and receive email. (This is the one i created by myself). So I really would like to know if it's necessary to create it and when will be the case I must need to create one. Is this for the time I need to use smart host?
Also, i would like to know is the default smtp virtual server responsible for both sending and receiving mail? in service, I see there is smtp service there, whatt does it need to do with the default smtp virtual server here?
