[Dovecot] Have problem with antispam plugin

[gerasew at gmail.com]

I downloaded the source code plug-in version 1.3 from 
http://johannes.sipsolutions.net/download/dovecot-antispam/
Unpack and make from this .config file:

     BACKEND=mailtrain
     DOVECOT=/usr/include/dovecot
     INSTALLDIR=/usr/lib/dovecot/modules/imap
     USER=root
     GROUP=root
     DEBUG=syslog
     DEBUG_VERBOSE=1
     PLUGINNAME=antispam


Dovecot cofing file:

     protocol imap {
       login_executable = /usr/lib/dovecot/imap-login
       mail_executable = /usr/lib/dovecot/imap
       mail_plugins = quota imap_quota antispam
     }

     plugin {
       antispam_mail_sendmail = /usr/bin/sa-learn
       antispam_mail_spam = --spam
       antispam_mail_notspam = --ham
       antispam_mail_tmpdir = /tmp
       antispam_trash_pattern_ignorecase = trash;Deleted *
       antispam_spam_pattern_ignorecase = junk;spam
     }


When move message into\from "Spam" folder get error:

     [SERVERBUG] failed to send email

In syslog:

Get sa-learn output from help this script:

     #!/bin/bash

     (
       id -a
       sa-learn
       rc=$?
       echo "exit code $rc"
       exit $rc
     ) > /tmp/antispam.out.$$ 2> /tmp/antispam.err.$$

antispam.err - contains output as "sa-learn --help"

So this means that the call comes without any parameters or with 
incorrect parameters.
I need this to work, please help.
