I set Email Accounts
B to reply with a "Vacation Response" every time a new email is received.
What would happen if Email Account
A sent an email to Email Account
Would the sending messages back and forth continue indefinitely? Or would something break down? Or would nothing at all happen?
Bonus: On "smart" servers, what could I do with the ability to forward or retrieve mail? (For example, Gmail supports "importing mail" and Forwarding mail in addition to Vacation Responses.)
