Binary package “dsbltesters” in ubuntu xenial

open proxy/relay testing utilities

 This package contains testing software configured to work with
 the DSBL ( or DSBL-compliant services. It
 enables you to send tests to servers based on spam that you
 receive. If those tests succeed, the results will reach the
 DSBL host in question, and the relay will be listed.
 Note: the original DSBL service has gone, it's not possible to
 submit nor place a query there.
