Blocklist use

How this blacklist works?

  • We collect spam reports from many victims of spam
  • Administrators of IP spam become notification
  • We add fresh spam IP to temporary blacklist bl.octopusdns.com
  • Every next spam reports to blacklisted IP renew blacklisting time

Checking DNSBL bl.octopusdns.com return positive record A - 127.0.0.2 when IP is actually on blocklist.

We suggest using our RBL list very carefully. Try not reject all messages confirmed as spam by bl.octopusdns.com, but only assign more percent possibility of spam.

Our recommended RBL servers are:

  • b.barracudacentral.org.
  • bl.spamcop.net.
  • zen.spamhaus.org.
  • cbl.abuseat.org.
  • psbl.surriel.com.
  • bl.octopusdns.com

Please donate our job if you are satisfied.

Small dns servers can use our blacklist for free. High Volume servers (more than 100 requests in 5 seconds) need monthly subscription.
