Rules for registering data in RBL.JP

The several black lists running here at RBL.JP are managed with the co-operating of volunteers. On this page we'll explain the rules for registering data in these black lists.

You can have a look at the Rejection diary (Japanese only) which is updated everyday by the staff at Hart Computer. You can look here to get a better idea of what kind of data is being registered in the blacklists under what kind of policies.

virus.rbl.jp

Volunteers registering data in this RBL will register the following kind of addresses:

  • The address of the PC/server that directly sent the virus-infected mail. The addresses of any machines that relayed the mail are not included.

    Addresses which are to be registered will be one of the following types; dial-up, ADSL connection or belong to commercial organization. ISP and rental server addresses will not be included but commercial addresses of machines which have been infected with a virus and have a static IP will be included.

    Addresses will automatically be deleted 2 days after being entered in the RBL.

    short.rbl.jp

    Volunteers registering data in this RBL will register the following kind of addresses:

  • The address of machines with a dynamic IP address that send spam.

  • The address of machines with a dynamic IP address that relay spam.

  • The address of machines with a dynamic IP address that use a dictionary-based attack method to send spam. You can find evidence of this in your maillog.

    Addresses to be registered will be either be dial-up or ADSL, whereby they are dynamically allocated a new IP everytime they connect to their ISP. Hence the name of the RBL - short - for short-term IP address allocation. Static addresses will not be registered.

    In the case where the mail server is your own, e-mails accumlating in the queue can be be a source of information. The kind of spam that will accumulate in the queue is where the To: and From: addresses both don't exist.

    Sometimes addresses that've been identified as being associated with a spammer from a URL in a spam or some other identifier will be registered in the short.rbl.jp but not always. If you wish to use an RBL which deals with spammers' servers we recommened bl.spamcop.net.

    Addresses will automatically be deleted 2 days after being entered in the RBL.

    all.rbl.jp

    all.rbl.jp combines the features of both virus.rbl.jp and short.rbl.jp. Data from both RBLs is merged automatically.

    If you wish to use virus.rbl.jp and short.rbl.jp on your mail server please only set all.rbl.jp and not both.

    Addresses will automatically be deleted 2 days after being entered in the RBL.

    url.rbl.jp

    Volunteers registering data in this RBL will register the following kind of domains:

  • Domains that you find in spam from URLs in the spam's body whereby the URL is directly related to the spammer himself or corresponds to a party which is somehow related to that spammer and where every sub-domain is also related somehow with the spammer.

  • Domains in the sender fields (From:, Reply-To:, Return-Path:) that directly relate to the spammer himself or a party which is related with the spammer.

    If there is a URL in the spam that links to a non-spammer related site then its domain name will not be registered.

    url.rbl.jp registers mainly domain names from URLs and not IP addresses but if the URL in the spam uses an IP address and not a hostname then this IP address may be registered.

    In the case where the mail server is your own, e-mails accumlating in the queue can be be a source of information. The kind of spam that will accumulate in the queue is where the To: and From: addresses both don't exist.

    Data will be automatically removed 60 days after the day of registration in the RBL.

    dyndns.rbl.jp

    Volunteers registering data in this RBL will register the following kind of domains:

  • Domains of URLs which use a free dynamic DNS service and the URL is found in a spam will be registered.

  • Domains of dynamic DNS services which do not require anything more than an e-mail address at the time of registration. This is because they don't demand enough information to try and help identify the individual registering.

    Domain names of dynamic DNS services regardless of whether they are in Japan or overseas can be registered.

    Even if you use a dynamic DNS service but your server has its own domain then usually it will not be registered in this RBL.
    There is no expiry on data in this RBL (ie. entries will not automatically be deleted after a certain number of days like the above RBLs). Use this RBL at your own discretion.


    General Warning

    It is our policy to try and not register normal mail servers belonging to ISPs and rental servers from which spam or virus-infected e-mails are relayed through but if such a server is detected as being infected itself with a virus itself it will be registered.

    There is a chance a mail server might mistakenly be registered in RBL.JP but checks are performed periodicially and mistaken entries are deleted. We cannot guarantee that 100% of all mistaken entries will be removed as the number of entries to be checked in the database get larger and larger.

    In the case a mail server has accidentally been added to the RBL you can apply to have it removed here.
