What is vspam.org?

vspam.org is a free, community-driven phishing intelligence clearinghouse. Mail operators, sysadmins, and security researchers submit and verify indicators of compromise (IOCs) — phishing URLs, malicious domains, command-and-control IPs, and spoofed email addresses. Every report is community-reviewed and confirmed before publication.

Confirmed threats are published to a real-time DNS blocklist (DNSBL) that mail servers can query during SMTP transactions, a REST API for automated lookups, and STIX/TAXII feeds for integration with SIEMs and threat intelligence platforms. The platform processes reports across four IOC types: URLs, domains, IP addresses, and email addresses.

How it works

  1. Submit — Report phishing URLs, suspicious domains, C2 IPs, or spoofed emails with evidence and source headers.
  2. Verify — Community members vote to confirm or dispute each report. Trust tiers weight votes by reporter reputation.
  3. Block — Confirmed IOCs are promoted to the DNSBL zone, API feeds, and STIX bundles within minutes.
  4. Query — Look up any indicator via the search bar, REST API, DNS query, or the mail policy agent.

Integration options

  • DNSBL — Query dnsbl.vspam.org from Postfix, Exim, or any MTA that supports DNS blocklists.
  • REST API — Programmatic access to reports, IOC lookups, voting, and statistics at api.vspam.org/api/v1/.
  • STIX/TAXII — Standards-based threat intelligence feeds for automated ingestion by SIEMs and TIPs.
  • Mail Agent — Lightweight Go sidecar that checks IOCs during SMTP policy evaluation with local BoltDB caching.
