Japan's own black list database system, the "RBL.JP Project" has been formally launched and is steadily progressing. We will be distributing information by means of a mailing list. We are still accepting applications (Japanese mail form) for volunteer programmers, web designers, database engineers, people who can translate RBL.JP documents into foreign languages and those knowledgagble about relevant legal issues. These are non-paid positions. Goto here for more about the recruiting of volunteers in English.

A tool written in PHP to encode to/encode from base64. You can use this to decode any spam that has its message encoded in base64.

DEAG
A tool to generate distorted GIF images out of your e-mail address. This image can display your e-mail address on your website in place of using the mailto:x@x HTML tag which can be used by spambots to collect addresses. Distortion is added to make the image only readable by humans.

About RBL.JP:

RBL.JP stands for Realtime Blackhole List Japan and is the domain name the server designated for this service.

RBL.JP is coordinated by Hart Computer Co. Ltd. as a volunteer group project staffed by technologists from across Japan. Our goal is to create a system that is more user friendly for Japanese than existing similar systems. Additionally we also plan to make this system such that it can be used by those outside Japan as well.

RBL.JP is a system that allows anyone, free of charge, to search for the addresses of servers known to send spam. Most Spam is usually sent by third parties from servers from which they are able to access. If we can block the mail traffic coming from these servers, we can effictively reduce the amount of spam. RBL.JP stores a great number of these addresses and respond to requests in real time. To use these functions requires only slight modifications to your server's configuration.

RBL.JP contains not only information about servers that are used by unauthorized third parties to send spam, but also servers that are known to distribute malicious spam. Use of this system allows you choose all or some of the funcitonality and thus you can determine the level of mail blocking to be used.
