	Hmm..  Not sure, but the code at the mailbox for return-recipient-to
	to do recipient address pickup was never very strong.  Most likely it
	just expected to get just the plain address at the header, not heaps
	of "MIME-2 (headers)" encoded stuff among which the return address sits.

	Have a look into the  mailbox  program where the header
	Return-Receipt-To: is recognized, and processed.

	Now the  return_receipt()  code starts its work by converting
	all instances of '\n', '\r', and '\t' chars to spaces.

	This should result into rather awkward single line of:
		to =?koi8-r?Q?....?= =?koi8-r?Q?.....?= <user@address>
	but it looks like only the first line made it thru as if
	the system were running older version of  ctlopen.c  et.al.,
	which did indeed split continued headers into multiple sublines
	previously.
