Overview
0spam RBL is the real-time blocklist from the 0spam project. Compared to the project's BL list, RBL has broader coverage but maintains equally strict listing standards. 0spam targets low false-positive rates, requiring multiple confirmations for every listing decision.
How It Works
0spam uses its own detection infrastructure combining spam traps and traffic analysis to identify spam sources. Their algorithm prioritizes precision β they'd rather miss some spam sources than incorrectly list legitimate senders.
How to Get Delisted
Visit 0spam.org to check status and submit removal requests. Given the high listing threshold, being listed typically indicates a real spam problem originating from your IP.
