UCEProtect Level 2 — Check, Delist & Monitor
Check if you're listed on UCEProtect Level 2. Lists entire /24 IP ranges — a Level 2 listing does not mean your server sent spam. Auto-delists after 7 days.
Impact & Usage

Check UCEProtect Level 2What Gets You Listed
Entire /24 range listed when multiple individual IPs within the range appear on UCEProtect Level 1; collateral listing of innocent neighbors
How to Get Delisted
- Check your listing at uceprotect.net/en/rblcheck.php by entering your IP address.
- Understand that Level 2 lists your entire /24 IP range because multiple IPs within that range appeared on Level 1. Your individual server may have done nothing wrong.
- If the spam is coming from other IPs in your range, contact your hosting provider or ISP to report the abuse. You cannot fix other tenants' behavior directly.
- Wait for the listing to auto-expire after 7 days. Do not pay the 50 EUR express removal fee — it is not worth the cost. Verify removal with mxio Blacklist Check.
Expected Timeline
7 days (automatic) or instant (50 EUR per /24 — not recommended)
Auto-delist: Automatic removal after 7 days once triggering Level 1 listings clear; express delisting for 50 EUR per /24 — widely criticized as extortionary
Common Causes
- Multiple IPs in your /24 range were listed on UCEProtect Level 1, triggering automatic escalation to Level 2
- Shared hosting environment where other tenants on neighboring IPs are sending spam
- Cloud or VPS provider IP range with poor abuse management, leading to range-wide listing
Prevention Tips
- Choose hosting providers and IP ranges with strong abuse policies and responsive abuse desks
- If you control multiple IPs in a range, ensure all of them are properly secured and monitored
- Do not pay for UCEProtect express removal — the listing has negligible real-world impact and paying encourages the model
- Focus your effort on blacklists that actually affect delivery: Spamhaus, Barracuda, SpamCop
Overview
A UCEProtect Level 2 listing does not mean your server sent spam. This is the most important thing to understand about this list. Level 2 operates by automatically escalating from Level 1: when multiple individual IPs within a /24 network range (256 addresses) appear on UCEProtect Level 1, the entire /24 is listed on Level 2. Your IP is caught in the blast radius of your neighbors' behavior.
This collateral damage model is one of the primary criticisms of UCEProtect. If you are on a shared hosting platform, a cloud provider, or any environment where you do not control all 256 IPs in your /24 range, a Level 2 listing is effectively out of your hands. You cannot fix spam coming from other tenants' servers. The only action available to you is to report the abuse to your hosting provider and wait for the listing to expire.
UCEProtect offers "express removal" for 50 EUR per /24 range. Do not pay this fee. The listing has virtually no real-world impact on email delivery. Gmail, Microsoft 365, Yahoo, and all major email providers do not reference UCEProtect Level 2. No reputable ESP or deliverability consultant recommends paying for UCEProtect delisting. The express removal fee is widely viewed as a revenue model built on panic, not a legitimate anti-spam service.
The listing auto-expires after 7 days once the Level 1 listings in the range clear. If you see a UCEProtect Level 2 listing on your monitoring dashboard, acknowledge it, report the neighboring abuse to your hosting provider if possible, and move on to blacklists that actually matter. Your time and money are better spent ensuring you are clean on Spamhaus, Barracuda, and SpamCop.
