The 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL) is a legacy IP-based blocklist that targets hosts reported for sending phishing emails. It operates as a DNSBL (DNS-based Blackhole List), using the lookup zone phishing.rbl.msrbl.net so mail server administrators can check a connecting IP address during filtering.
According to its FAQ, the primary goal of this blacklist is to reduce the server resources needed to process mail and scan for malicious content, not to block email by itself. Administrators using this list should treat it as part of a scoring system rather than an automatic reject rule. The FAQ says IPs are listed for three days after the last virus, phishing, or similar notification.
Who runs 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL)?
The MSRBL Phishing blacklist (and other MSRBL lists) is operated by Chris Burton from 8086.net, a consultancy based in the United Kingdom.
Is 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL) still active?
Treat this blocklist as legacy infrastructure. The official MSRBL website still names phishing.rbl.msrbl.net as its phishing RBL, but its Check DB page says the lookup interface is currently unavailable, and public DNSBL status data reports that msrbl.net appears to be offline.
For mail administrators, that changes the practical advice: do not add this RBL to a new mail filtering configuration, and remove stale msrbl.net checks from existing systems if they produce DNS failures, timeouts, or unexpected rejections. A dead or unreliable DNSBL can slow SMTP sessions and generate inaccurate blacklist results.
How do I get removed and delisted from 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL)?
Removal from the 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL) was designed to be automated. Under the published FAQ, an IP address is delisted after three days have passed since the last report of malicious activity. The current Check DB page is unavailable, so there is no dependable manual delisting route to use when the list is unreachable.
Before waiting for expiry or asking a recipient to change their filtering, identify and resolve the underlying issue that caused the listing. Run a malware scan on the affected host, review outbound mail logs for phishing content, rotate compromised credentials, and confirm that the IP is an authorized sending source. If you use Suped, check Suped's DMARC source view to confirm whether the IP belongs to an approved sender or an unknown source before you chase blocklist removal.
If a bounce references msrbl.net and your IP is not sending phishing, contact the recipient through another channel and ask their mail provider to remove stale msrbl.net checks. MSRBL does not intercept mail itself, so delivery failures come from the recipient system's blacklist configuration.
What's the impact of being listed on 8086 Consultancy MSRBL Phishing Realtime Blacklist (RBL)?
The impact of being on this specific blacklist is usually low because the operator advises administrators not to block mail outright and public DNSBL status information indicates the zone is no longer dependable. The risk rises when a receiving system still queries msrbl.net, treats a lookup error as a failed reputation check, or uses the listing as an automatic rejection rule.
- A listed IP can receive a higher spam score, which increases the chance that mail lands in the recipient's junk or spam folder.
- A mail server that still queries an unavailable RBL can delay SMTP handling while DNS lookups time out.
- A strict recipient configuration can reject mail from any IP on this blacklist (or blocklist), which causes a bounce.
- A bounce that names msrbl.net usually points to the recipient's filtering setup, because MSRBL does not intercept or block mail itself.
