# Looks like the system mailbox is OK, now quit the mailer.
# Let me remind you, folks, withing the mailer itself we just read the
# message #1 and marked it as deleted.
# So, we quit the mailer...
# We sincerely expect to see the messages #3 and #4 being left in the mailbox.
# We would understand if the message #2 will reappear in the mailbox
(though it's hard
# to "accept" this).
# So, we quit:
& q
New mail has arrived.

# From what it has just said we guess that it did restore the message #2
in the system
# mailbox. Oh, well - we did not expect this to be a real mail system, did we?
# So, how is our mailbox doing?
# Message #2 looks OK, message #4 looks fine, too.
# BUT SEE WHAT HAS HAPPENED TO THE MESSAGE #3!
