Package: wnpp Severity: wishlist * Package name : greylist-milter Version : 1.4 Upstream Author : Emmanuel Dreyfus <[EMAIL PROTECTED]> * URL : http://hcpnet.free.fr/milter-greylist/ * License : BSD Description : grey listing filter for sendmail
Grey listing works by assuming that contrarily to legitimate MTA, spam engines will not retry sending their junk mail on a temporary error. The filter will always temporarily reject mail on a first attempt, and accept it after some time has elapsed. see also: http://groups.yahoo.com/group/milter-greylist/message/251
