The 8086 Consultancy MSRBL Images Realtime Blacklist (RBL) is an IP-based blacklist (or blocklist) that specifically lists hosts found to be sending mail which contains spam images.
The 8086 Consultancy MSRBL Images Realtime Blacklist (RBL) is an IP-based DNS blocklist that specifically lists hosts found to be sending emails containing spam images. It is one of several blocklists operated by MSRBL (Mail Server Real-time Blacklists). The primary policy of this blacklist is not to block emails directly, but rather to provide system administrators with a freely available list of IP addresses that have been identified as sources of image spam.
Administrators of mail servers can query the zone images.rbl.msrbl.net to identify and filter or reject mail from these listed IPs. The goal is to reduce the server resources needed to process unwanted emails, particularly those heavy with image content. This blocklist operates by identifying IP addresses that have been reported for sending spam, and the listing is based on these reports.
This specific realtime blacklist is operated by Chris Burton of 8086 Consultancy, an IT consultancy based in the United Kingdom. They manage a suite of MSRBL blocklists targeting different types of malicious email activity.
Removal from the 8086 Consultancy MSRBL Images blacklist is an automated process. An IP address will be automatically delisted 3 days after the last report of spam activity was received for it. There is no manual delisting request form; you must wait for the automatic expiry.
Before you wait for the delisting to occur, it is crucial to identify and resolve the underlying issue that caused the listing. Here are the recommended steps:
The impact of being listed on the 8086 Consultancy MSRBL Images RBL is considered low. It is not a blacklist used by major mailbox providers like Google or Microsoft. However, it may be used by smaller internet service providers, independent mail server administrators, and companies who wish to add an extra layer of filtering for image-based spam.
If your IP address is on this blocklist, you may experience email delivery failures to recipients whose mail servers use this specific list. While the overall impact on your deliverability may be minimal, a listing here is a clear indicator of a problem with your sending reputation that needs to be addressed to prevent being listed on more impactful blacklists.
