DroneBL is a blacklist of abusable and "rooted" machines (IP addresses). DroneBL is used by ISPs and others as part of a blackhole strategy to prevent phishing attacks and other forms of network abuse. A positive listing by DroneBL is not always indicative of spam, as it could be due to an open proxy or more serious issue.
If you have been listed by DroneBL, please also check your server for potential drones, trojans, backdoors, or misconfigured proxies, as email spam may be indicative of a more severe issue.
Drone Bl Reports Open Relays
Relay/Proxy-based Blacklists typically list email servers and/or hostnames that are sending Unsolicited Bulk Email (UBE) that is clearly from email addresses that are not hosted on the server or that do not match the SMTP Banner/Hostname of the Email Server, commonly referred to as an Open Relay. An Open (Mail) Relay is an SMTP server configured in such a way that it allows anyone on the Internet to send e-mail through it, not just mail destined to or originating from known users.
Drone Bl Reports Virus Infected Sources
Virus-based Blacklists are those that will list single IP Addresses (or hostnames) of email servers that have sent Spam traffic that is generated by some form of a Virus, Malware, Trojan, or "botnet" infection in a network. This is often a result of a user visiting a webpage that houses an infection and downloads malware on a PC which then creates a "mini SMTP" server used to hijack account information, and send bulk email to recipients in the Users' email address book. It can affect the actual machine housing the "Email server platform" or on a local PC which is allowed to connect to the Email Server IP Address on SMTP port 25.
Drone Bl Requires A Manual Delisting Request
This blacklist does support a manual request to remove or delist your IP Address from their database. Please note that removal requests that are submitted without addressing the core problem will likely result in your IP Address or Domain being relisted in that database, which can cause subsequent problems and extended listing periods without release.
Your Email Deliverability is in Jeopardy!
Blacklisting is a sign that you are not actively managing your email deliverability. Other technologies - SPF, DKIM and DMARC are now just as important to get your email placed in the Inbox of your recipients. If you aren’t managing email deliverability, your message may never be heard.
