Qmail smtp-auth can't recognize Vpop users

[Fossy_01]

Hello:

In one of my servers I have installed Qmail, Vpop, RoundCube, and Courier Imap. All working perfect!, but now I need to use email clients like Outlook, Eudora, etc., and yesterday I patch Qmail with smtp-auth and make some modifications, but Vpop users can't recognize:


[root@ks24740 html]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 webmail.onuba.com ESMTP

cHJ1ZWJhCg==
535 authorization failed (#5.7.0)

My /var/qmail/supervise/qmail-smtpd/run is:

exec /usr/local/bin/tcpserver -p -R -x /home/vpopmail/etc/tcp.smtp.cdb -u92 -g91 -v -c100 0 smtp /usr/local/bin/rblsmtpd -r bl.spamcop.net /var/qmail/bin/qmail-smtpd /bin/cmd5checkpw /usr/bin/true 2>&1

Please, any help?.

Thanks!!
