Or why when setting up an email account does the mail app send the domain name you enter to apple?
I don't know for sure, but when you set up an email account, based on the address you supply, the Mac does try to auto configure stuff for a wide range of popular email services. I'm guessing it's probably sending off the address to search for that auto configuration information.
