+
+Hi,
+
+the above mentioned server is used as an open relay to send vast amounts
+of XMPP spam to different unrelated servers, such as the server I
+administer.
+
+Spammers are using the In-Band-Registration feature on that server to
+create a large number of accounts, and to send mass messages to my
+users.
+
+Please contact the server owner to disable In-Band-Registration, to take
+measures against spam relaying or to shut down the XMPP service.
+
+Also please find attached a list of the bot accounts and an excerpt of
+the spam messages sent to my service.
+
+$SUMMARY
+
+
+Kind regards,
+
+$NAME
