Qmail Probleme

Ich habe mich mal wieder rangesetzt und versucht mir einen Mailserver mit qmail aufzusetzen und bin da nach der Anleitung http://www.gentoo.org/doc/de/qmail-howto.xml vorgegangen
Jetzt steh ich aber vor dem Problem mit der Authentifizierung beim SMTP, bei mir kann derzeit jeder drauf und ich seh einfach nicht welche “SMTP-AUTH” Variablen ich da entkommentieren soll

hier ist meine conf-smtpd

# Configuration file for qmail-smtpd
# $Header: /var/cvsroot/gentoo-x86/mail-mta/netqmail/files/conf-smtpd,v 1.1 2006/02/12 18:42:33 hansmi Exp $

# Stuff to run before tcpserver
#QMAIL_TCPSERVER_PRE=""
# Stuff to run qmail-smtpd
#QMAIL_SMTP_PRE=""
# Stuff to after qmail-smtpd
#QMAIL_SMTP_POST=""

# this turns off the IDENT grab attempt on connecting
TCPSERVER_OPTS="${TCPSERVER_OPTS} -R"

# fixcrio inserts missing CRs at the ends of lines. See:
# http://cr.yp.to/ucspi-tcp/fixcrio.html
# http://cr.yp.to/docs/smtplf.html
# DO NOT enable this when you are using SSL/TLS (USE=ssl)!
#QMAIL_SMTP_PRE="${QMAIL_SMTP_PRE} fixcrio"

# You might want to use rblsmtpd with this, but you need to fill in a RBL
# server here first, see http://cr.yp.to/ucspi-tcp/rblsmtpd.html for more
# details
#QMAIL_SMTP_PRE="${QMAIL_SMTP_PRE} rblsmtpd -r RBL-SERVER"

# If you are interested in providing POP or IMAP before SMTP type relaying,
# emerge relay-ctrl, then uncomment the next 2 lines
#QMAIL_TCPSERVER_PRE="${QMAIL_TCPSERVER_PRE} envdir /etc/relay-ctrl relay-ctrl-chdir"
#QMAIL_SMTP_PRE="${QMAIL_SMTP_PRE} relay-ctrl-check"
# In /etc/courier-imap/authdaemonrc add the next line to the end:
#authmodulelist="${authmodulelist} relay-ctrl-allow"
# Then in /etc/courier-imap/{imapd,imapd-ssl,pop3d,pop3d-ssl}
# Add this at the end
#PRERUN="${PRERUN} envdir /etc/relay-ctrl relay-ctrl-chdir"

# This next block is for SMTP-AUTH

# WARNING: If you've installed qmail with USE=noauthcram, and you want to use
# the following programs, you proably need to install them.

# Example using cmd5checkpw
# See the manpage for cmd5checkpw for details on the passwords
#QMAIL_SMTP_CHECKPASSWORD="/bin/cmd5checkpw"
QMAIL_SMTP_CHECKPASSWORD="/var/vpopmail/bin/vchkpw"

# Example for checkpassword-pam (emerge checkpassword-pam)
# Don't forget to make /usr/bin/checkpassword-pam sticky (see README.auth)
#QMAIL_SMTP_CHECKPASSWORD="/usr/bin/checkpassword-pam -s system-auth"

[[ -n "${QMAIL_SMTP_CHECKPASSWORD}" ]] && {
        [[ -z "${QMAIL_SMTP_POST}" ]] && QMAIL_SMTP_POST=/bin/true
        QMAIL_SMTP_POST="${QMAIL_SMTP_CHECKPASSWORD} ${QMAIL_SMTP_POST}"
}

es wäre schön wenn ihr da eine Lösung kennt
