Sieve interpreter & Dovecot ManageSieve

The Pigeonhole project provides Sieve support as a plugin for Dovecot's Local Delivery Agent (LDA) and also for its LMTP service. The plugin implements a Sieve interpreter, which filters incoming messages using a script specified in the Sieve language. The Sieve script is provided by the user and, using that Sieve script, the user can customize how incoming messages are handled. Messages can be delivered to specific folders, forwarded, rejected, discarded, etc.

Dovecot Managesieve Server is a service used to manage a user's Sieve script collection.

Installing Dovecot and sieve on a vpopmail + qmail server

Overview

Dovecot is an open source IMAP and POP3 email server for Linux/UNIX-like systems, written with security primarily in mind. Dovecot is an excellent choice for both small and large installations. It's fast, simple to set up, requires no special administration and it uses very little memory.
