qmail + smtp auth is not going

[jeller2]

I have a problem with Qmail

telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 blackwidow.lzh ESMTP
auth plain
334
user terminator@blackwidow.lzh
501 malformed auth input (#5.5.4)
user terminator@blackwidow.lzh
502 unimplemented (#5.5.1)

my config is

/var/qmail/control/conf-smtpd

# This next block is for SMTP-AUTH
# This provides the LOGIN, PLAIN and CRAM-MD5 types
# the 'cmd5checkpw' used in $QMAIL_SMTP_AUTHCHECKPASSWORD supports CRAM-MD5
# and reads it's data from /etc/poppasswd
# see the manpage for cmd5checkpw for details on the passwords
# uncomment the next four lines to enable SMTP-AUTH
QMAIL_SMTP_AUTHHOST=$(<${QMAIL_CONTROLDIR}/me)
[ -z "${QMAIL_SMTP_POST}" ] && QMAIL_SMTP_POST=/bin/true
QMAIL_SMTP_CHECKPASSWORD="/var/vpopmail/bin/vchkpw"
QMAIL_SMTP_POST="${QMAIL_SMTP_AUTHHOST} ${QMAIL_SMTP_CHECKPASSWORD} ${QMAIL_SMTP_POST}"


I hope someone can help me
