The 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL) is an IP-based blocklist that identifies hosts known for sending phishing emails, helping mail server administrators filter this malicious content.
The 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL) is an IP-based blocklist that specifically targets hosts known for sending phishing emails. It operates as a DNSBL (DNS-based Blackhole List), providing a list of IP addresses that mail server administrators can query in real-time to help identify and filter potential phishing attacks.
According to its policy, the primary goal of this blacklist is not to outright block email but to help reduce the server resources needed to process mail and scan for malicious content. Administrators using this list are advised to use it as part of a larger scoring system rather than for immediate rejection of messages. IPs are typically listed on this blocklist for three days after the last phishing activity was detected from the address.
The MSRBL Phishing blacklist (and other MSRBL lists) is operated by Chris Burton from 8086.net, a consultancy based in the United Kingdom.
Removal from the 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL) is an automated process. An IP address will be automatically delisted after three days have passed since the last report of malicious activity. There is no manual delisting form or process.
Before waiting for the automatic removal, it is critical to identify and resolve the underlying issue that caused the listing. The operators recommend running a comprehensive virus and malware scan on the affected computer or server to ensure your systems are no longer compromised and sending phishing emails.
The impact of being on this specific blacklist is generally considered low. This is because the list's operators explicitly advise administrators against using it to block mail outright. Instead, they recommend using the blacklist as a component of a wider anti-spam strategy. However, the exact impact can vary.
