The 8086 Consultancy MSRBL Virus Realtime Blacklist (RBL) was an IP-based DNSBL (DNS-based blocklist) that listed hosts found sending virus emails. The lookup zone for this blacklist was virus.rbl.msrbl.net. Current public DNSBL references report MSRBL.NET as offline, so a mail rejection that still references this zone usually points to a stale receiving-server check rather than an active listing.
MSRBL's own policy advised administrators not to use its blocklists to reject all mail outright. The intended use was to reduce the resources required to process email and check for virus content, while systems still used a dedicated antivirus product. That policy made the list a filtering signal, not a complete blocking decision.
Is MSRBL still active?
Current DNSBL reference material reports MSRBL.NET as offline. If a bounce message or mail log still names virus.rbl.msrbl.net, the practical fix sits with the receiving mail system. The recipient or their email provider should remove msrbl.net from the blacklist (blocklist) checks used to reject or score incoming mail.
For senders, this means an MSRBL reference is not a reliable sign of a current virus infection by itself. Treat it as a configuration clue, then review your outbound mail logs and endpoint security to confirm that no infected host is still sending mail through your infrastructure.
Who runs 8086 Consultancy MSRBL Virus Realtime Blacklist (RBL)?
This particular blacklist was operated by Chris Burton of 8086.net Consultancy, a company based in the United Kingdom.
How do I get removed or delisted from 8086 Consultancy MSRBL Virus Realtime Blacklist (RBL)?
MSRBL's stated removal policy was automatic delisting 3 days after the last report of malicious activity. There was no manual delisting form to submit. Because current DNSBL reference material reports MSRBL.NET as offline, a rejection that still cites msrbl.net is usually handled by removing the stale DNSBL check from the receiving server.
Before treating the listing as a stale blocklist result, confirm that your systems are not sending virus mail. Use these checks:
- Run a comprehensive virus scan on computers, servers, and any host that sends mail through your domain or IP space.
- Review outbound mail logs for unusual volume, unexpected sender addresses, repeated attachment campaigns, or unauthorized SMTP connections.
- Secure compromised systems by patching exposed services, rotating credentials, and disabling unauthorized mail-sending paths.
- If a recipient still rejects mail because of msrbl.net, ask the recipient or their email provider to remove the inactive MSRBL DNSBL check from their mail server.
What's the deliverability impact of being listed on 8086 Consultancy MSRBL Virus Realtime Blacklist (RBL)?
The impact of an 8086 Consultancy MSRBL Virus Realtime Blacklist (RBL) reference is generally low today because current DNSBL references report MSRBL.NET as offline, and the original operators advised administrators not to use the list as a hard blocking rule. A direct rejection that cites msrbl.net points to a receiving server that still has an old DNSBL check configured.
The old MSRBL policy also allowed Internet Service Providers (ISPs) to request that their mail server IPs not be listed, which reduced the risk of legitimate relay traffic being treated as infected. For current troubleshooting, focus on removing stale blacklist or blocklist references at the receiver and checking that your own infrastructure is not sending virus mail.
