dovecot - Feb 2013 - Sieve not filtering

Hello,

I installed a few weeks ago the Dovecot package on a Debian stable 
along with postfix, everything works fine except the sieve filter. I 
followed the howto found on the internet (google: debian postfix dovecot 
sieve). I'm able to view and modify sieve rules with roundcube or 
thunderbird plugins, but the rules are not applied when a message 
arrives and all messages arrive in INBOX. Here is the content of my 
configuration files concerning sieve :

dovecot.conf
protocols = imap imaps managesieve

    protocol managesieve {
      listen = *:2000
    }

protocol managesieve {
   mail_executable = /usr/lib/dovecot/managesieve

   managesieve_max_line_length = 65536

   managesieve_logout_format = bytes=%i/%o

}

protocol lda {
   postmaster_address = postmaster at babelouest.org

   mail_plugins = sieve
   mail_plugin_dir = /usr/lib/dovecot/modules/lda

   log_path    info_log_path    syslog_facility = mail
}

plugin {
   sieve_dir=~/Maildir/sieve
}


And the postfix/main.cf config file contains for dovecot sieve the 
following

maibox_command = /usr/lib/dovecot/dovecot-lda -f "$SENDER" -a 
"$RECIPIENT"
dovecot_destination_recipient_limit = 1
virtual_transport = dovecot

I also tried the command
mailbox_command = /usr/lib/dovecot/deliver

it didn't work either...

Is there somthing so obvious that I didn't see it ?

Thanks in advance

Better to post 'dovecot -n' which is the active config.

http://wiki.dovecot.org/LDA/Sieve/Dovecot

Not sure what the default was for the active script in the old Dovecot versions
as 'sieve_dir' is the upload directory for scripts to be referenced (see
Wiki). Active config will tell.

You may raise logging levels and it will tell you what happens when the LDA
tries to spawn sieve:
