+ * If http_received_header_encrypt is configured, the IP address and the
+ * host name of the added Received: header is encrypted with 3DES, to
+ * protect information that some could consider sensitve, yet their
+ * availability is a must in some circumstances.
+ *
+ * Such an encrypted Received: header might look like:
+ *
+ * Received: from DzgkvJBO5+bw+oje5JACeNIa/uSI4mRw2cy5YoPBba73eyBmjtyHnQ==
+ * [my0nUbjZXKtl7KVBZcsvWOxxtyVFxza4]
+ * with HTTP/1.1 (POST); Thu, 14 May 2009 19:17:28 +0200
+ *
+ * In this example, the two encrypted components are the sender host name
+ * (DzgkvJBO5+bw+oje5JACeNIa/uSI4mRw2cy5YoPBba73eyBmjtyHnQ==) and the IP
+ * address (my0nUbjZXKtl7KVBZcsvWOxxtyVFxza4).
+ *
+ * Using this tool, they can be decrypted into plain text:
+ *
+ * $ bin/decrypt_received.php 'my0nUbjZXKtl7KVBZcsvWOxxtyVFxza4' \
+ * > 'DzgkvJBO5+bw+oje5JACeNIa/uSI4mRw2cy5YoPBba73eyBmjtyHnQ=='
+ * 84.3.187.208
+ * 5403BBD0.catv.pool.telekom.hu
+ * $
+ *
+ * Thus it is known that this particular message was sent by 84.3.187.208,
+ * having, at the time of sending, the name of 5403BBD0.catv.pool.telekom.hu.
+ *
+ * If (most likely binary) junk is shown, then
+ * - either the encryption password has, between the time the mail was sent
+ * and `now', changed, or
+ * - you are dealing with counterfeit header data.
