  Yes,  I have thought of revising it someday, but have spent my cycles at
  other topics recently (vacationing and now something called "work").

  The revised interface could be something like:

	ctrlcode smtpcode-continued text line
	ctrlcode smtpcode last text line

  That is, separate control code driving the behaviour, then just sender
  visible text lines.

  The ctrlcode could be something like:

	0	ok, accept (default reply: "250 Ok")
	1	discard (default reply: "500 content not liked")
	2	freeze  (default reply: "250 delivered into freezer")

  and more carefull response parser making sure that there indeed is
  a numeric control code, with space following it, and then 3 numeric
  chars with space or "-" (continued line, or not).

  If the approver subroutine yields something else, discard the message
  and yield "400 problem with the content policy subsystem"
