It's the chicken and the egg problem. A mail reader is of no use
without an SMTP agent. A SMTP agent isn't of any use without a mail
reader. So, inorder to break the deadlock, you start by using an
existing SMTP agent (aka sendmail), and write the reader. Then someone
writes the agent.

That might be an option, for compatibility reasons. Maybe someone
might want to be able to hand off all of his Email to someone on a
less advanced system. Besides, what would he stores his mail in if it
wasn't a file? Remember, we don't have a POS yet.
