Drone BL Blacklist Removal

DroneBL is a widely used blacklist designed to identify abusable and “rooted” machines, primarily IP addresses, that may be involved in network abuse and phishing attacks. This article aims to provide a comprehensive understanding of DroneBL, including its purpose, the types of listings it includes, the importance of addressing underlying issues, and the steps to request removal.

What is DroneBL?

DroneBL serves as a blacklist utilized by ISPs and other entities to implement a blackhole strategy, preventing network abuse and phishing attacks. It focuses on identifying machines or IP addresses that exhibit suspicious behavior or are susceptible to abuse. It is important to note that a listing on DroneBL does not solely indicate spam activity but could be a result of an open proxy or more severe issues.

Types of Listings in DroneBL

Relay/Proxy-Based Listings:
DroneBL includes email servers or hostnames that function as open relays, allowing unsolicited bulk email (UBE) to be sent from email addresses not hosted on the server or not matching the SMTP banner/hostname. Open relays enable anyone on the internet to send email through them, which can be exploited for spam purposes.

Virus-Infected Source Listings:
DroneBL also lists IP addresses or hostnames of email servers that have been identified as sources of spam traffic generated by viruses, malware, trojans, or botnet infections. This occurs when a user’s device becomes infected, creating a “mini SMTP” server to hijack account information and send bulk email to recipients. It can affect both the email server platform and local PCs connected to the infected network.

Importance of Addressing Underlying Issues

If your IP address has been listed on DroneBL, it is crucial to investigate and address potential issues within your server or network. While email spam may be the primary concern, it could indicate more severe problems such as drones, trojans, backdoors, or misconfigured proxies. Taking immediate action to identify and resolve these issues will help prevent further listings and mitigate potential risks.

Steps for Removal

Unlike some other blacklists, DroneBL does support manual removal requests. However, it is essential to address the core problem before submitting a delisting request. Failure to do so may result in your IP address or domain being relisted, leading to prolonged listing periods and subsequent issues. To initiate the removal process, follow the guidelines provided by DroneBL, ensuring that the underlying issues have been resolved beforehand.

Best Practices for Email and Network Security

Regular Security Audits: Conduct periodic security audits to identify vulnerabilities and potential threats within your network infrastructure. Implement necessary security measures and keep software and systems up to date to minimize the risk of compromise.

Malware Protection: Deploy robust antivirus and antimalware solutions across your network to detect and prevent infections caused by viruses, trojans, or other malicious software.

Secure Configuration: Ensure that your email server and network devices are configured securely, with appropriate access controls, firewalls, and intrusion detection systems in place.

User Education: Educate users about the importance of safe browsing practices, avoiding suspicious websites, and refraining from downloading or opening suspicious email attachments to prevent malware infections.

Monitoring and Incident Response: Implement proactive monitoring systems to detect any anomalous behavior, unauthorized access attempts, or signs of compromise. Have an incident response plan in place to promptly address and mitigate any security incidents.


Understanding DroneBL and its impact on email and network security is crucial for maintaining a healthy online environment. By addressing underlying issues, following best practices for email and network security, and promptly requesting removal from DroneBL, you can safeguard your network from potential abuse and phishing attacks.

Preventing Listing on the KISA Blacklist:

To minimize the risk of being listed on the KISA Blacklist and to maintain a healthy email communication environment, it is crucial to adopt good email practices. Consider the following guidelines:

  1. Verify Email Addresses: Before sending any outreach emails, validate the email addresses to ensure their authenticity. This can help prevent sending emails to non-existent or incorrect addresses, reducing the chances of being flagged as spam.
  2. Minimize Unnecessary Emails: Sending excessive or irrelevant emails can increase the likelihood of being marked as a spammer. Focus on meaningful and relevant communication to avoid triggering spam filters.
  3. Mind Your Language: Be mindful of the words and phrases you use in your email drafts. Avoid using spam-triggering words or phrases that can raise suspicions and increase the risk of being flagged as spam.
  4. Control Sending Volume: Keep your email sending volume at a moderate level to avoid overwhelming email servers and appearing as a potential spammer. If you have been consistently using the same email address for at least 30 days, limit your daily sending to a reasonable range, such as 30-50 emails.
