A person's e-mail address is his or her login name @ the name of a DNS domain with an MX record. Login names can be first names, last names, initials, and all kinds of other names. Suppose that a large company decided too much e-mail was getting lost because people did not know the login name of the recipient. Is there a way for them to fix this problem without changing DNS? If so, give a proposal and explain how it works. If not, explain why it is impossible.
