# taRgrey

S25R + tarpitting + greylisting - a tarpit + greylisting policy server.

> taRgrey is a patch that makes postgrey into a tarpitting policy server.

> Tarpitting means response delay for blocking spam.

> taRgrey is designed to decrease false positives.

-- http://k2net.hakuba.jp/targrey/index.en.html

> The concept of the Selective SMTP Rejection (S25R) anti-spam system, [...] is

> so simple that a mail server accepts SMTP accesses from mail relay servers

> but rejects direct SMTP accesses from end-user's computers.
