The URIBL Black Domain Name Blacklist is a domain-based blocklist (or blacklist) containing domain names used by spammers that are found in the body of unsolicited bulk and commercial emails, with a stated goal of zero false positives.
Check if you are listed on URIBL Black Domain Name Blacklist
The URIBL Black Domain Name Blacklist is a domain-based blacklist (or blocklist) that contains domain names found within the content of unsolicited bulk and commercial emails, often referred to as UBE or UCE. It is a real-time list that is frequently updated as new data becomes available. Its primary policy goal is to maintain a high level of accuracy and achieve zero false positives, making it a reliable source for filtering spam.
This blocklist is widely used by system administrators and anti-spam software to complement existing spam-fighting measures. Notably, it is enabled by default in the popular open-source software SpamAssassin and is also integrated into several commercial anti-spam products. URIBL distributes its data through various methods, including Public DNS lookups, RSS Feeds, and Data Feeds via rsync for high-volume users. If you are making too many queries to the public DNS mirrors, you may receive a '127.0.0.255' response, which indicates your usage is too high and a dedicated Data Feed may be required.
Who runs URIBL Black Domain Name Blacklist?
The blacklist is operated by URIBL.COM, a service dedicated to collecting and distributing data about domain names associated with spam. It's important to note that URIBL.COM does not register or host domains, nor does it have the authority to suspend them. The organization simply provides data to help others identify and filter unwanted email.
How do I get removed and delisted from URIBL Black Domain Name Blacklist?
If your domain is listed on this blacklist, you must use the official lookup form on the URIBL website to request removal. You will be required to register for an account before you can submit a delisting request. You can find the form here. Before you request removal, please be aware of the following points:
Do not send emails requesting delisting. All removal requests must go through the web form; email requests will be ignored.
URIBL will not provide specific reasons for a listing. They do not offer feedback loops or disclose the trap data that led to the domain being blacklisted.
Whitelisting is not available by request. The internal whitelist is used by URIBL's team and does not reflect a domain's reputation.
Ensure you are listed on URIBL and not another service like SURBL. The URIBL lookup form may show SURBL listings for convenience, but they are separate projects and URIBL cannot delist you from SURBL.
What's the impact of being listed on URIBL Black Domain Name Blacklist?
The impact of being listed on the URIBL Black Domain Name Blacklist is considered medium. Because it is used by SpamAssassin and other commercial anti-spam systems, a listing can cause your emails to be filtered into the spam folder or rejected outright by a significant number of mail servers.
A more severe consequence is that some domain registrars use URIBL's data to automatically suspend (or place on hold) domain names found on the blocklist. If your domain is suspended, you will need to resolve the issue directly with your registrar, as URIBL has no control over this action.
