+To enable us to investigate errors or problems you should provide us
+with the following information (or as much of it as possible):
+
+ * the IP,
+ * the Time (including timezone),
+ * the Message-Id,
+ * the Addresses you sent from and to,
+ * anything else that you think would help
+
+We maintain a system which receives and sends more than 1,000,000
+mails a day. Without the information above we have little chance of
+finding out what went wrong.
