Distributed Realtime Black List
DRBL node Gremlin.RU
Q: Remove me from your list!!! NOW!!!A: First of all, stop yelling. It won't help you anyway.
The second step towards getting removed is to understand what exactly happened to you. If you find your address in one of the working zones, than it is completely senseless to try to contact the owner of such a zone. And it is twice stupid to contact the maintainer of this or other DRBL sites, because we doesn't have any authority on the other DRBL node's zones. Don't try to reach any 'chief DRBL administrator' because there's no such officer in DRBL project. In fact, there's no central power here at all. If you're confused, try reading the rest of this FAQ.
Well now to the point. If you really want to get off the DRBL lists, what you need is to find out which voteing zones are listing you. These are the only hand-written and human-controlled sources where your address come to the other zones from. Once you're done, contact the people responsible for these zones. Click here for the list of known zones and their respective contacts. But you are strongly encouraged to check the next question before doing so.
Q: I'm not a spammer, why do they list me?
A: The DRBL project's main mission is to provide a mechanism to share local filters written for particular mail servers by their administrators. There are very different sites in the project, from large ISPs to private hobbysts' mailers. Each administrator has his/her own policies and considerations on what he/she doesn't want to accept. The only limitation is that the administrator must use his own zone himself. But you don't really need to be a spammer to get to someone's local filter. It's not an abuse to make a filter: when you own a server, it is your right and your privilege to make decisions what mail to accept and what to reject. Noone is forced to use anyone's voting zone, it's a matter of trust and private considerations. But noone can be forced not to use any filters as well.
This mean you can't demand to remove your address. You only can ask to do so. Please keep it in mind contacting the DRBL zones' administrators.
Q: What is DRBL?
Q: How does it work?
*.57.168.192 IN A 127.0.0.2 IN TXT "Spammers network blocked"This blocks mail from 192.168.57.0/24 network giving "Spammers network blocked" as a comment.
The next step is to set up policies used to generate WORK zone. You should decide which VOTE zones will be used and the measure of trust to their administrators. There should be a scalar value of weight assigned to each zone and a threshold value, which is used to generate a WORK zone. Each address from one or more zones gives weight equal to a sum of weights of all zones this address belongs to. If the weight of an address is greater then or equal to a threshold value, then the address is put to a WORK zone.
Suppose we maintain network-1.ru network and have to use DRBL. So we create vote.drbl.network-1.ru and work.drbl.network-1.ru . Then we decide to generate our WORK zone using information from some other networks - vote.drbl.network-2.ru, vote.drbl.network-3.ru, vote.drbl.network-4.ru, vote.drbl.network-5.ru and vote.drbl.network-6.ru. The administrator of network-2 is our old fellow and, therefore, a trusted person. Less known person is the administrator of network-3, so less we trust, and finally, we don't know the administrators of network-4 , network-5 and network-6, but there are no reasons for us not to trust them (is there are such reasons, we simply won't use their zones at all). Then we decide to use a threshold value of 1 (or 100, to assign weights in a percentage of trust, or some other value) and assign the following weights to zones:
vote.drbl.network-1.ru 1 vote.drbl.network-2.ru 1 vote.drbl.network-3.ru 0.8 vote.drbl.network-4.ru 0.4 vote.drbl.network-5.ru 0.4 vote.drbl.network-6.ru 0.4Now, if some address apears in our own VOTE zone vote.drbl.network-1.ru or in a fully trusted VOTE zone vote.drbl.network-2.ru maintained by our fellow, then this address will be automatically put in our WORK zone, and incoming mail from this address will be rejected.
If some address is banned in network-3, it will not be put into our WORK zone immediately - it's necessary for it to be banned in some other network. For example, if some address is banned in network-3 and network-5, then its total weight will be 1.2 , which exceeds the threshold value. In this case we suppose that blocking given address somewhere else is a good reason to do the same.
Finally, if none of the network-1, network-2 or network-3 have blocked some given address, then it will be put into our WORK zone only in case of all three networks will vote for it.
Q: Why do I need it?
Q: Why distributed?
Q: So, how do I get out of all these voting zones?
A: Surely, you have received a bounce message similar to this:
Whether to use generated work zones as a source for creating other work zones?
What software do I need?
A: There are two different schemes of a DRBL node. Click here for details.
How should I select zones and set weights?
Ok, I've made a voting zone. Are there any restrictions for what I can
I can't (or don't want) to create my own DRBL node. May I still
use it to protect my network?
Well, I have set up my own DRBL node. What should I do to make it
available to other networks?
A: You can contact one of the current DRBL members and ask to annonce your zone to the others (please do not contact many of the DRBL members at once -- remember, they hate spam!). There's a closed mailing list used by several of the DRBL members, any of them can annonce your zone to the (almost) whole project.
Please include names of VOTE and WORK zones, address of name server capable of AXFR zone transfer from any address, and the name of the network your zone is used in. Also it would be a good thing to describe your policy of creating the VOTE zone.
Last advise: think before you do. Only in that case your VOTE zone could be popular and have a respectable weight.
