Dovecot ManageSieve Server
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 standard protocol, 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.
Dovecot's ManageSieve support is distributed in a separate package. Currently it also requires patching Dovecot sources, but this won't be necessary anymore in Dovecot v2.0. Dovecot's ManageSieve implementation is part of the Pigeonhole project. There exists also an alternative pysieved ManageSieve server that works with Dovecot.
