Spamikaze is a collection of programs to easily build a DNSBL, also known as a spam block list.


Unlike some other spam block systems, Spamikaze does no tests for open proxy or open relay vulnerabilities.

Spamikaze is passive and completely driven by mail coming into a system's spamtrap addresses. In order to reduce the false positives (depending on your point of view) inherent in such a scheme, Spamikaze uses some regular expressions to weed out obvious non-spam mails. It can also use whitelists to exclude known mail servers from being listed.

Spamikaze is free software, available under the GPL.

If you plan to run a spam block list, Spamikaze should make your life easier.


Spamikaze development happens slowly and the git head is quite stable. It is recommended that people use Spamikaze's latest version directly from the GitHub repository.

A number of DNSBLs use Spamikaze in production.
