Problems with postfix and procmail

Hi,
I have a problem with messages to multiple users on my serwer.

I have a virtual domains on mysql.

Directories /home/mail/domain.pl/username

if mail is for 3 users in syslog postfix is called 3 times but with
same pipie number.

where is the problem ?
Maybe someone could help me with write a code to explode users and
domains from ^To header and place message to right folders ?

main.cf:

procmail unix - n n - - pipe
flags=R user=vmail:vmail argv=/usr/bin/procmail -t -m /etc/procmailrc
${recipient}

procmailrc :

SHELL=/bin/sh
VERBOSE=yes
UMASK=007
ADRES=$1
ADRES=`echo $ADRES | /usr/bin/tr A-Z a-z` # force lowercase username
DOMAIN=`echo "${ADRES}" | cut -d @ -f 2 | cut -d "<" -f 2| cut -d">" -
f 1| cut -d @ -f 1`
USER=`echo "${ADRES}" | cut -d @ -f 1 | cut -d "<" -f 2| cut -d">" -f
1| cut -d @ -f 1` # get username for local delivery
SMIETNIK=/home/mail/filtered/
LOGFILE=/home/log/procmailnew.log # for testing & troubleshooting
INCLUDERC=/home/mail/${DOMAIN}/${USER}/.procmailrc # allow users to
create their own recipes
LOGNAME: ${LOGNAME}"
MAILDIR=/home/mail/${DOMAIN}/${USER}/

$MAILDIR


thanx
