Here's an extract from a recent messaage we got about one of our customers from someone at an NZ ISP.
The above server was detected trying to deliver mail from known bogus addresses to our servers and subsequently tested positive to a basic spam relaying check.
As an open spam relay, it has been added to the rbl.shub-inter.net DNS blackhole, used by a few dozen ISPs worldwide and around 10 ISPs within NZ. This will already be affecting your connectivity.
The Shub-inter.net blackhole was created as an adjunct to the rbl.maps.vix.com blachole, which is used by approximately 10,000 servers worldwide. Its purpose is to provide filtering against sites which are open relays, but which have not made it into the vix.com list.
Addition to the vix.com list is only a matter of time if the server is left as-is.
Removal from the shub-inter.net list is only achieved by fixing the open server.
I have a number of questions for the group: 1) Is anyone here part of this arrangement? 2) Are people here happy that a group of individuals, ISPs etc are operating in this way? I'd prefer to see 'offenders' being approached and given the opportunity to mend their ways before unilateral action is taken. 3) Has anyone any opinion on whether a group acting in this way forms a cartel which restrains trade? I feel it might well do.
