Dovecot Sieve is a fully rewritten Sieve implementation for Dovecot v1.2 and newer. The main reason for rewriting the Sieve engine was to provide more reliable script execution and to provide better error messages to users and system administrators. This implementation is part of the Pigeonhole project.

At first you need to download sources, unpack it and make or edit configuration script:

root@feniks:/home/soft/dovecot# su - soft
soft@feniks:~% cd dovecot 
soft@feniks:~/dovecot% wget http://www.rename-it.nl/dovecot/1.2/dovecot-1.2-sieve-0.1.17.tar.gz
soft@feniks:~/dovecot% gtar -zxf dovecot-1.2-sieve-0.1.17.tar.gz
soft@feniks:~/dovecot% cp drf_sieve-1.2-0.1.12_conf drf_sieve-1.2-0.1.17_conf
soft@feniks:~/dovecot% vi drf_sieve-1.2-0.1.17_conf

Configuration and compilation with use of script:

soft@feniks:~/dovecot% ./drf_sieve-1.2-0.1.17_conf
