Courier-imap

Комрады,
Не могу догадаться каким образом приучить courier-imap использовать Maildir`ы не в домашней директории пользователя, а в /var/spool/mail/.
стоит связка EXIM+Sasl+courier-imap, авторизация идет через Active Directory.

Конфиг:
sirius courier-imap # cat pop3d

PIDFILE=/var/run/pop3d.pid
MAXDAEMONS=100
MAXPERIP=4
POP3AUTH="LOGIN"
POP3AUTH_ORIG="PLAIN LOGIN"
POP3AUTH_TLS=""
POP3AUTH_TLS_ORIG="LOGIN PLAIN"
POP3_PROXY=0
PORT=110
ADDRESS=0
TCPDOPTS="-nodnslookup -noidentlookup"
LOGGEROPTS="-name=pop3d"
MAILDIRPATH=/var/lib/mail

# Hardwire a value for ${MAILDIR}
MAILDIR=
# Put any program for ${PRERUN} here
PRERUN=
# Put any program for ${LOGINRUN} here
# this is for relay-ctrl-allow in 4*
LOGINRUN=
