The Anti-Spam SMTP Proxy (ASSP) server project is an Open Source, Perl based, platform-independent transparent SMTP proxy server available at SourceForge.net that leverages numerous methodologies and technologies to both rigidly and adaptively identify e-mail spam. ASSP is easy to set up because it requires only minor changes to the configuration of your Mail Transfer Agent. == Features == Some ASSP's features are: * Bayesian analysis * Penalty Box (PB) trapping * DNSBL/RBL (Realtime Blackhole Listing) * URIBL (Uniform Resource Identifier Black Listing) * Multi-level SPF (Sender Policy Framework) validation and blocking * SRS (Sender Rewriting Scheme) fix-up * Session Delaying/Greylisting and connection response delaying * Sender validation and recipient validation * Multi-level attachment blocking (based on block lists or allow lists) * As well as multiple RFC validation mechanisms. * Multi-threaded (Since version 2.x) * Platform independent (Written in Perl) 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Anti-Spam SMTP Proxy」の詳細全文を読む スポンサード リンク
