[Dovecot] sieve plugin

[Андрей]

I try to cinfigure dovecot run sieve scripts on incoming mail.

In my dovecot.conf:

        <...>
        protocol lda {
        # Address to use when sending rejection mails.
                postmaster_address = [EMAIL PROTECTED]
        
        # Hostname to use in various parts of sent mails, eg. in Message-Id.
        # Default is the system's real hostname.
                hostname = vpcit.ru
        
        # Support for dynamically loadable plugins. mail_plugins is a space 
separated
        # list of plugins to load.
        #mail_plugins =
                mail_plugin_dir = /usr/lib/dovecot/modules/lda
        
        # Binary to use for sending mails.
        #sendmail_path = /usr/lib/sendmail
        
        # UNIX socket path to master authentication server to find users.
                auth_socket_path = /var/run/dovecot/auth-master
        
        # Enabling Sieve plugin for server-side mail filtering
        mail_plugins = cmusieve
        }
        
        <...>
        
        plugin {
                sieve = /var/mail/%d/%1n/%n/.dovecot.sieve
        }

Then i set experiments on my maildir.
In /var/mail/vpcit.ru/d/dukenukem i created script .dovecot.sieve:

        require "fileinto";
        if header :comparator "i;ascii-casemap" :contains "Subject" "sieve 
check"
        {
                fileinto "Trash";
                stop;
        }

Permissions on /var/mail/vpcit.ru/d/dukenukem are:
        drwx------  5000 mail

So script should put every message that has "sieve check" subject into Trash 
folder.

1) Trash folder isn't created, should i create it manually?
2) Even when i create Trash folder and make 777 permissions to maildir, 
nothing happens (message is dropped into inbox dir)
3) Should i configure my Kontact (KMail) e-mail client some way?
4) What i've done incorrect?

The mail system works fine at the moment for receive and send, trouble only 
with sieve scripting.

Yours faithfully,
Andrey.
