Email Spam TestSorbs DUHL Blacklist: Effective Steps to Remove Your IPThe Sorbs DUHL Blacklist specifically targets dynamically allocated IP addresses associated with spam and malicious emails, which can affect email deliverability.
The SORBS (Spam and Open Relay Blocking System) DUHL (Dynamic User and Host List) is a DNS-based Block List (DNSBL) operated by Proofpoint, Inc. This list includes over 12 million host servers known for sending or relaying spam, phishing attacks, and other malicious emails. The Sorbs DUHL blacklist specifically targets servers with dynamically allocated IP addresses, which are more likely to be used for spam due to their transient nature. Additionally, the sorbs blacklist is an important tool for identifying and mitigating spam threats.
Major mailbox providers like Google and Microsoft typically don’t rely on external blacklists like Sorbs for their spam filtering decisions, but being listed can still affect your email deliverability.
The Sorbs DUHL blacklist blocks potential threats from dynamically assigned IPs. Knowing how this SORBS DUHL blacklist work operates and how to manage it helps maintain a healthy email system.
Start by confirming if your IP or domain is listed on the Sorbs DUHL blacklist using their website’s lookup tool. Visit the site and navigate to the lookup section.
Enter your IP address and complete the captcha. The tool will quickly inform you if your IP block is blocked, giving you the information needed for further action.
If you discover that your IP is listed, don’t panic. The Sorbs DUHL blacklist doesn’t automatically expire; you must actively take steps for delisting. The process involves identifying and resolving issues with your IP and submitting a delisting request.
Ensure your IP is not dynamically assigned. If it is, switch to a static IP and resolve any spam issues. After addressing these, submit a delisting request on the Sorbs website.
Since the Sorbs DUHL lists servers with dynamically allocated IP addresses, switch to a static IP first. Using mail servers with dynamic IP assignment is generally not advisable for email deliverability. For B2B cold emails, consider services like Google Workspace or Office365 for better deliverability.
If your IP assignment is controlled by your host or internet service provider, request their assistance with removal, though success is not guaranteed.
Once you’ve switched to a static IP, you can proceed to submit a delisting request. Create a secure account on the Sorbs website. The delisting request usually needs to come from the ISP or regional internet registry PoC. Include your contact information, the IP address, and details about the delisting request in the form.
You must show that the IP address is now assigned statically or that the spam issue has been resolved. The review process can take a few days to a week, so monitor your status regularly. If there’s no response, follow up after a week to 10 days.
If your request is denied, review the feedback, improve your remediation efforts, and gather more documentation for resubmission.
