Welcome to CamelDNS TestRBL

Welcome to the CamelDNS FREE TestRBL Service.

This Service is ONLY to be used for testing a new implementation of a RBL Tagging or Blocking system. It MUST NOT (and can not) be used in a live environment to check Emails for being Blacklisted. TestRBL is only for helping you ensure your implementation is working exactly as you expect prior to adding 'real' RBL's.

Our TestRBL has been setup for general public use and can help you check your setup prior to sending it live with real traffic passing through and accidentally getting rejected or altered.

Please remember that this list is a Test System and a Temporary one, and the ONLY way to add or remove an IP address is via our web pages. Please do NOT Email us requesting an IP address be removed. They will automatically be removed after 24 hours from being added. The only other way for removal is to enter the IP address into this Form(IPv4): and it is as simple as that.

What is an RBL?

A "Relay Block List / Real-Time Blackhole List / Registered Black List" (*delete as appropriate) typically is a database listing of IP addresses known to Relay SPAM/UCE, though not exclusively, there are other uses.

The purpose of the *List is to provide access to a list of IP addresses that a network can use to filter it's traffic, typically Email, and usually to reject it. However (as in the examples here) you can also use the system to 'Tag' Emails that are listed in whichever RBL's you choose.

The merits of using any *List is at best highly argued throughout the Internet these days. We leave these merits completely up to yourself for deciding if RBL systems are useful, and whether the collateral damage is with an acceptable range, but you are obviously already aware of RBL's and their impressive collective merits and strength in rejection of confirmed SPAM/UCE.

Why create a Public Test RBL?

Adding and Removing IP Address?

Adding and Removing of any IP you choose is simple, and done in real time (watch out for your DNS Caches though). The Add/Remove is done through this simple to use Form. You can also 'Check' to see if your IP is listed via the same form. Similarly if you include the link in any Emails you deliberately reject, you can also see a similar response to places like SpamCop.net

So how is the TestRBL used?

There are at least two answers, first there is outright 'Rejection' of traffic (usually emails) thats sending IP is listed in any of a number of Free and Commercial RBL systems. And then there is 'Tagging', which is typically used for Email traffic. If you look at our examples and links we show you some quick methods to implement and then test this. Though the TestRBL can easily be used with your own custom, free, or commercial systems your installing.
