Overview
0spam (rbl.0spam.org) is a DNS-based blacklist that detects spam through its own network of sensors and spam traps. It maintains several sub-lists for different types of abuse (IP-based, URL-based, domain-based). 0spam is designed to be responsive — listings are added quickly when spam is detected and expire quickly when the spam stops.
Why You Might Be Listed
- 1Your IP was detected sending spam to 0spam's network of spam traps
- 2Your domain or URLs appeared in spam messages captured by 0spam sensors
- 3Bulk unsolicited email was detected from your IP address
Step-by-Step Removal
Check your listing
Visit 0spam.org and use their lookup tool to check your IP or domain against their various blacklists (RBL, BL, NBL, URL, DBL).
Stop the spam source
Identify what is generating spam from your server. Check for compromised accounts, open relays, misconfigured mailing lists, or malware. Fix the root cause.
Request removal or wait for auto-expiry
0spam provides a self-service removal form on their website. After resolving the spam issue, submit a removal request. Alternatively, listings auto-expire approximately 24 hours after the last spam detection.
Verify clean traffic
After removal, send a few test emails and verify that your IP remains clean. Monitor with IsMyEmailBlacklisted to catch any relisting early.

https://0spam.org/Important Tips
- ●0spam has multiple sub-lists (RBL, BL, NBL, URL, DBL). Check all of them, as your IP may appear on more than one.
- ●The fast auto-expiry makes 0spam relatively forgiving. Focus on fixing the spam source and the listing will clear itself.
- ●0spam is less widely used than Spamhaus or Barracuda, so prioritize those if you are listed on multiple blacklists.
