Subject: XMPP spam report for {domain} / {ips} XMPP domain: {domain} Server: {srv} Jabber IP: {ips} 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}
