+#	attempt to return a doubly-bounced email to a postmaster
+#	jr@terra.net, 12/4/97
+#
+#	invoke by creating an mail alias such as:
+#		doublebounce:	"|/usr/local/sbin/doublebounce"
+#	then adding this line to your sendmail.cf:
+#		O DoubleBounceAddress=doublebounce
+#
+#	optionally, add a "-d" flag in the aliases file, to send a
+#	debug trace to your own postmaster showing what is going on
+#
+#	this allows the "postmaster" address to still go to a human being,
+#	while bounce messages can go to this script, which will bounce them
+#	back to the postmaster at the sending site.
+#
+#	the algorithm is to scan the double-bounce error report generated
+#	by sendmail on stdin, for the original message (it starts after the
+#	second "Orignal message follows" marker), look for From, Sender, and
+#	Received headers from the point closest to the sender back to the point
+#	closest to us, and try to deliver a double-bounce report back to a
+#	postmaster at one of these sites in the hope that they can
+#	return the message to the original sender, or do something about
