thanks!!!
a small note. it'd be better to use [Virtual] section's uid,gid?
another problem it's not working for me:-(
any tip would be useful.
the relevant config:
---------------------------------
[Dovecot]
# Path to Dovecot's auth socket (do not set unless you're using Dovecot
auth)
mux = /var/spool/postfix/private/auth
master = /var/run/dovecot/auth-master

# Path to sievec
sievec = /usr/libexec/dovecot/sievec

# Where in user directory to store scripts
scripts = .pysieved

# What user/group owns the mail storage
uid = 101
gid = 12
---------------------------------
sockets:
---------------------------------
# ls -ln /var/spool/postfix/private/auth /var/run/dovecot/auth-master
srw-rw---- 1 101 12 0 Jul 18 14:20 /var/run/dovecot/auth-master
srw-rw---- 1  89 12 0 Jul 18 14:20 /var/spool/postfix/private/auth
---------------------------------
and the result of run:
---------------------------------
# python pysieved.py -p /var/run/pysieved/pysieved.pid -c
/etc/pysieved.ini -d -d -d
