	Don’t use on a mailbox with old messages left unread and unanswered.

	Simply subclass ``AutoReplyer``, define the undefined class attribute,
	and call the ``run`` method on an instance. This loops until you stop the script
	(using Ctrl+C, typically) or until an error occurs, like a network failure.
