The 8086 Consultancy MSRBL Combined Realtime Blacklist (RBL) is a combined IP blocklist that aggregates multiple blacklists to identify servers sending viruses, phishing emails, spam, and spam-related images.
The 8086 Consultancy MSRBL Combined Realtime Blacklist (RBL) is an IP address based blocklist that aggregates data from several more specialized lists. As a 'combined' blacklist, it includes IP addresses that have been detected sending various types of malicious or unsolicited email. Mail server administrators use this blocklist to help identify and filter incoming mail from potentially problematic sources.
This specific blacklist (or blocklist) is a composite of the following individual MSRBL zones:
Interestingly, the operators of the MSRBL advise against using their lists to outright block mail. Instead, they suggest using the data to score emails, which helps reduce server load from virus and spam checking. This policy indicates a focus on filtering and resource management rather than complete rejection of mail.
The MSRBL project is operated by Chris Burton of 8086 Consultancy, a consultancy based in the United Kingdom.
The delisting process from the 8086 Consultancy MSRBL is automated. An IP address will be automatically removed from the list 3 days after the last malicious activity was detected from it. This means that once the underlying issue is resolved, the listing will expire on its own.
Before you wait for the automatic removal, you must ensure your system is no longer sending spam or malicious mail. This typically involves running a full virus and malware scan on your computer or server to identify and clean any infections.
You can check the status of your IP address and see why it was listed by using the lookup tool on their website. This tool provides information and may offer a manual removal option if the criteria are met.
The impact of being listed on this blacklist is generally considered low. This is primarily because the organization running the list recommends that mail administrators do not use it to strictly reject email. However, any listing on a blacklist (or blocklist) can still cause email deliverability issues.
