# 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.
