The 8086 Consultancy MSRBL Spam Realtime Blacklist (RBL) is an IP-based blacklist that lists hosts observed sending email containing spam. It operates under the DNSBL zone name spam.rbl.msrbl.net. MSRBL also publishes related zones for virus mail, phishing mail, image-spam messages, and a combined list.
Unlike some blocklists, MSRBL's policy is not to encourage outright blocking as the default action. The operators describe the service as a way for mail and web server administrators to reduce resources spent processing unwanted or malicious traffic. In practice, administrators use the list as an input for scoring, filtering, or extra scanning rather than as the only reason to reject mail.
Check operational status before relying on it
MSRBL's public website still lists spam.rbl.msrbl.net, but administrators should verify that the DNSBL is answering current DNS queries before using it to reject or score mail. Stale DNSBL checks create false failures when a blocklist (blacklist) stops answering correctly or has been retired.
If a bounce message mentions msrbl.net, first confirm whether the recipient's mail server still queries that zone. If the query is stale, failing, or returning unreliable data, the recipient's administrator should remove the msrbl.net check instead of sending the sender through a delisting process that does not exist for the Spam RBL.
Who runs 8086 Consultancy MSRBL Spam Realtime Blacklist (RBL)?
This blacklist (or blocklist) is run by Chris Burton of 8086.net Consultancy, an IT consultancy based in the United Kingdom.
How do I get removed and delisted from 8086 Consultancy MSRBL Spam Realtime Blacklist (RBL)?
Removal from the 8086 Consultancy MSRBL Spam Realtime Blacklist (RBL) is automated. MSRBL says IP addresses are listed for 3 days from the last spam, virus, phishing, or related abuse notification. For the Spam RBL, the practical delisting path is to stop the source of spam and wait for the listing to expire.
Before waiting for automated removal, investigate and resolve the issue that caused the listing. If the source remains active, the IP can be listed again on this blocklist and on other blacklists.
- Review outbound mail logs for sudden volume spikes, repeated recipients, unfamiliar sender accounts, and new sending hosts.
- Run virus and malware scans on computers and servers that send email.
- Secure the mail server against unauthorized access, open relaying, weak passwords, and exposed submission ports.
- Check web forms, CMS plugins, contact forms, and scripts that can send mail.
- Use Suped's DMARC reporting to confirm the sending source and SPF/DKIM results before changing DNS records or server rules.
The MSRBL FAQ refers users to its Check DB page for status checks. If that page is unavailable or the DNSBL no longer answers reliably, use your own logs and the 3-day expiry window as the remediation path.
What's the impact of being listed on 8086 Consultancy MSRBL Spam Realtime Blacklist (RBL)?
The impact of being listed on the 8086 Consultancy MSRBL Spam RBL is generally low. MSRBL tells administrators not to use its blocklists as the only basis for rejecting mail. It recommends scoring, extra scanning, or filtering decisions instead.
That means many systems that still query this blacklist will not reject your email outright. They can place mail in spam, apply extra scanning, or add a negative reputation score. If the recipient system has a stale msrbl.net check, the failure is on the recipient-side configuration and should be fixed there.
A listing still deserves investigation because spam sent through an authenticated or approved source can damage sender reputation beyond one blocklist. Confirm the source, stop the spam, then watch for fresh complaints or authentication failures.
