And what is the actual problem you want to solve by this limit. Sending messages to several users itself does not seem like a problem. > I think the only way > would be to limit the number of messages you can send to different > recipients in one second. Jabberd2 has a limiter of how many bytes per second can user send. When hit it throttles the connection and does not accept any more bytes for a period of time. > If you send messages to more than 2 recipients within a second all > additional messages are dopped. Dropping messages does not seem like a good policy. You should just throttle the connection or bounce packets back with 'policy-violation' type error, and text description explaining what policy was violated. > Is there a way to achive this behavior with jabberd2?

But there is a packet counter for every connection (used for packet count logging), so it should be fairly easy to implement one. Just copy the bytes-per-time limiter and change the field it uses from bytes to packets. :-) -- Tomasz Sterna Instant Messaging Consultant : Open Source Developer http://tomasz.sterna.tv/ http://www.xiaoka.com/ -- To unsubscribe send a mail to jabberd2+unsubscr...@lists.xiaoka.com
