Distributed Sender Blackhole List
The DSBL lists contain the IP addresses of servers which have relayed special test messages to listme@listme.dsbl.org; this can happen if the server is an open relay, an open proxy or has another vulnerability that allows anybody to deliver email to anywhere, through that server. Note that DSBL itself doesn't do any tests; it simply listens for incoming test messages and lists the server that delivers the message to DSBL's mail server.
