What is blocklist.de?
blocklist.de is a community project fed by fail2ban reports from participating servers: SSH and mail brute-force attempts, spambot behavior, DDoS sources. bl.blocklist.de is the combined zone. A listed IP has been observed attacking someone, which for a mail sender almost always means a compromised host, a leaked credential or a bot on the network.
The Delist page offers a self-service pause of seven days, meant to give you time to clean the machine; if attacks continue after that, the listing returns. The operator publishes no fixed turnaround beyond the pause.
How serious is a blocklist.de listing?
Standard: a smaller footprint, used mainly as a scoring signal by some receivers. Fix the cause it points at; weigh the listing itself calmly. The lookup at www.blocklist.de is the reference for whether you are listed today.
Why your IP got listed
What the operator lists: Attack reports: SSH/Postfix brute force, spambots, DDoS sources.
How to remove your IP from blocklist.de
- 1
Look the IP up at www.blocklist.de
The operator's own lookup shows whether the IP is listed and, where the list publishes reasons, why. Third-party checkers can lag or misread the zone.
- 2
Fix the cause before you ask
Attack reports: SSH/Postfix brute force, spambots, DDoS sources. A removal request while the cause is live is the fastest route to a repeat listing, and repeat listings are slower to clear.
