Projects / Spey


Spey is an SMTP proxy that sits between your existing mail server and the outside world, blocking spam using a greylisting technique. It is simple, lightweight, easy to install and configure, requires minimal changes to your existing mail server, is completely independent of which mail server you're using, and extremely effective. The author's spam intake has dropped from over a hundred messages a day to about 5. It uses the Sqlite database library as a backend.

            Release Notes: This version has finally fixed that horrible random-lockup-on-startup problem that was manifesting itself on some libc/pthread combinations. Domain verification now no longer happens on trusted or authenticated sessions (which means it will now accept submissions from Outlook and Outlook Express, which are buggy). SSL sessions are no longer considered automatically authenticated.
