Just a heads up incase you dont already know...
Yet another mob of clueless f'wits running an RBL why cant these deadshits just drop the DNS entries rather than piss off the rest of the world, not that I ever used them, but I'm sure plenty of unfortunate folks do, or at least did because they missed the news they are no longer an active RBL. This is another reason I only trust reputable RBL's lke spamcop, sorbs njabl and spamhaus. I'll never use any other.

If you are blocking at the MTA level using this site you are probably not receiving any mail as a result of this change. Best regards, |

It is perfectly logical that the "deadshits" would want to do something so that they do not continue to be bombarded with DNS queries from different deadshits that have not removed ORDB from their RBL config.

I already stated what they could do in my original post which of course you selectively did not quote, it is afterall what 99% of all other defunct RBLs have done over the years. -- Cheers Res mysql> update auth set Framed-IP-Address='127.0.0.127' where user= 'troll'; |

You are wanting the deadshits to drop the DNS query traffic for their now defunct RBL, correct? (Presuming yes.) A simple TCPDump (tcpdump -xXnNi eth0 -s 0 host 87.51.32.6) while querying (nslookup 127.0.0.2.relays.ordb.org 87.51.32.6) will shed some light on the subject. # tcpdump -xXnNi eth0 -s 0 host 87.51.32.6 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on eth0, link-type EN10MB (Ethernet), capture size 65535 bytes 20:01:18.959078 IP aaa.bbb.ccc.ddd.45560 > 87.51.32.6.53: 11470+ A? 127.0.0.2.relays.ordb.org.

Considering that the DNSBL closed in December 2006 and that someone is still using them, exactly what else do you expect them to do? The only people they're "pissing off" are those who after 15 months didn't have the sense to remove the checks against that DNSBL. Seems to me as if you're among the clueless ones. |

For the sake of this discussion, let's say that each country code will send one query per second. That means that there will be 167+ kbps of inbound DNS (query) traffic until everyone decides to update their RBL list. That translates to 1.8+ GB of traffic a day or 54.1+ GB of traffic a month of inbound DNS queries per day for a service that is now defunct. It is very likely that this traffic will very slowly taper off over a very long time. Let's consider the reply traffic. The reply traffic will be 397+ kbps of outbound DNS (reply) traffic. This translates to 4.2+ GB of traffic a day or 128.8+ GB of traffic a month of outbound DNS replies per day for a service that is now defunct. So if we combine the inbound queries and outbound replies, ORDB will have 564+ kbps of DNS traffic. This translates to 6.1+ GB of traffic a day or 183+ GB of traffic a month of DNS traffic for a service that is now defunct. So, would you rather drop 54.1 GB of traffic a month for the next how ever many months (open ended until everyone removes relays.ordb.org from their config) or would you rather have 183 GB of traffic for one month. I will even go so far as to say that you will not even have a full 183 GB of traffic because you have done something to ensure that people will react to what you did with in a matter of days. You play with the numbers and and see what you would want to do long term if you were facing this amount of traffic. Just imagine what it would be like if the rate of queries was higher than one per country code per second... Grant. . . . |

And both your recommendation and your claim about 99% of other defunct "RBL's" (RBL is not a generic term used by anyone with half a clue) demonstrate that you don't know what you're talking about. To not be simply a liar, you'd have to identify at least 400 defunct DNSBL's... There's a big problem with shutting down a high-volume DNS zone, in that the queries keep coming. Imbeciles (like anyone still querying ORDB) keep pounding away and if the zone wasn't planned out for termination from the start, there's a good chance that there are no good options for harmless shutdown. http://www.ietf.org/internet-drafts/...cklists-01.txt discusses this, as did the prior version. The issues have been discussed at length on the ASRG list and in other spam-focused fora and people who have tried to do the right things (which DO NOT include pushing the problem upstream to the gTLD roots) have not reported promising results from doing so. ORDB was very public about their shutdown. Anyone running a mail server still using them now deserves a long closed-door meeting with The Boss and HR and a big guy from Security with a large cardboard box. Letting a mail server sit that way for 15 months doing pointless DNS queries on every message is a demonstration of incompetence. (and no, I do not have much sympathy for anyone who set up a mail filtering system thinking it didn't need regular adjustment. Some flavors of ignorance require concrete lessons to overcome. ) -- Now where did I hide that website... |

It is despite the thoughts of the few usual suspects in here, totally irresposible, they had to realise the traffic (50GB p/mth is nothing for DNS) risks when they kick off an RBL (and yes cole maybe people in YOUR part of the world dont, but most in this region and europe that I know *do* use the term generically, live with it, not that I care one way or another). Grant it is irresponsible of the postmasters in private companies for not reviewing every RBL's web site or following the trolling tripe in usenet groups to ensure they are still working, it is their own fault they are not nerdy geeks who live for RFC's and whatever else isnt it, its also their fault for not having access to knowing or understanding what might have been setup by an IT contractor 5 years ago, that has enver given them any issues so have had no need to bring them "back in". It's not all as black and white as you think, maybe it is not so horrendous what has happened here but in the case of osirus or whatever it was called, that was, completely, as Joe did that without warning to anyone, thats just plain childish, and there was some other group of wannabes who did the same several years ago as well. I wont respond to cole (any further) or stussy for as per usual they result to personal insults at which time I stopped reading their posts, as that says all it needs to say about them. -- Cheers Res mysql> update auth set Framed-IP-Address='127.0.0.127' where user= 'troll'; |
