Or why when setting up an email account does the mail app send the domain name you enter to apple?
It's part of the automatic configuration settings. When you first set up a new email address using "Add other Mail Account" in Mail.app, it just asks your for your name, email address, and the password for the account. It then sends the domain to Apple to get the imap/pop3/smtp servers and other configuration information for that domain, if it is available, so the user doesn't have to enter them all separately. It's part of a good UI.
