Pigeonhole ManageSieve Server
==============================

The :ref:`Pigeonhole project <sieve>` provides `Sieve
<http://sieve.info/>`_ support for Dovecot, which allows users to filter
incoming messages by writing scripts specified in the Sieve language (:rfc:`5228`).
The Pigeonhole ManageSieve service is used to manage a user's Sieve
script collection. It has the following advantages over doing it directly via
filesystem:

* No need to let users log in via FTP/SFTP/etc, which could be difficult
  especially with virtual users.
* ManageSieve is a :rfc:`standard protocol <5804>`,
  so users can manage their scripts using (hopefully) user-friendly ManageSieve
  clients. Many webmails already include a ManageSieve client.
* Scripts are compiled before they are installed, which guarantees that the
  uploaded script is valid. This prevents a user from inadvertently installing
  a broken Sieve script.
