SBL Delisting Procedure

To request the removal of an SBL listing, the ISP to whom the listed IP address belongs must contact the SBL Team, by email, using the dynamic 'mailto' link visible on the SBL record page. The SBL Team operates 24 hours a day, seven days a week and normally removes listings quickly once notified by the ISP that the spam problem has been terminated. [1]

It is important to only contact the SBL Team address and not other Spamhaus addresses, as the Spamhaus Project consists of a number of distinct teams each with a particular role and make up. Spamhaus teams include but are not limited to: the SBL team, the XBL team, the PBL Team, the DBL Team, the ROKSO Team, the European Review Team. Only the SBL Team has access to and can handle removal of SBL listings.

It is essential that the spam issue the listing concerns has been terminated before asking for the removal of the listing. If the SBL Team have reason to believe the issue is ongoing they can not remove the listing. [2]


If for some reason even though the issue was terminated there remains some residual problem which does not satisfy the SBL Team that the listing can be removed, the issue can be referred to Spamhaus' European Review Team for reevaluation. The European Review Team also has the responsibility for reviewing and handling disputes of SBL listings which are alleged to be incorrect.

The procedure for removing an SBL listing starts at the specific listing's online record, an SBL web page detailing what is listed and why. At the end of each SBL record page is a section titled "Removal Procedure". The Removal Procedure section gives the email address for the SBL Team and the Subject reference for the removal request.

Each SBL record specifies the reason for listing the IP Address or IP Range. Normally this will be due to being a direct source of spam, hosting a landing site or other services implicated or determined to be behind the spam. Normally each SBL record also contains evidence in the form of a sample of a spam message received or a link to a web site advertised in a spam, or contains DNS Trace Evidence showing the results of DNS analysis on the domain or IP range and/or Whois records.

Special handling is employed for showing evidence of
spam sent to spamtraps or evidence supplied by trusted 3rd party intelligence. Spamhaus obtains samples of spam from a number of reliable sources including Spamhaus' own Spamtraps. In order to protect the usefulness of these sources, the source will not be revealed and parts of spam samples deemed to uniquely identify the source can and will be redacted. [3]




[1] Where we have a proven working relationship with any Internet Service Provider, the SBL team implicitly trusts the Internet Service Provider's Abuse Manager and will normally remove listings on the Abuse Manager's word that the reason for listing has been corrected or terminated.

[2] In the case of SBL listings of IPs under the control of known (ROKSO-listed) professional spammers, where listings are often made preemptively based on the gangs past performance and history, an SBL listing will normally remain in place until the gang has been completely removed from the ISPs' network.

[3] Spamhaus can not divulge the e-mail addresses of Spamtraps or of trusted users who supply spam evidence. A request for such addresses, so that the bulk email sender can wash them from his list, is analogous to one who either intentionally or unintentionally sends pornography to minors, who then asks for a list of those minors so he will not continue to commit the crime. The responsibility for complying with Spamhaus SBL policy and preventing UBE being sent begins and ends with the bulk email sender.
