SASL NTLM authentication failed

    Hello everybody!


    I am running in another problem. I am trying to connect via SMTP to the i-mscp Server but the mails are not processsing.


    The /var/log/mail.log says:


    Code
    1. Apr 23 13:52:43 server postfix/smtpd[9482]: warning: hostname HSI-KBW-xxx-xxx-xxx-xxx.hsi.kabelbw.de does not resolve to address xx.x.xx.xxx: Name or service not known
    2. Apr 23 13:52:43 server postfix/smtpd[9482]: connect from unknown[xx.x.xx.xxx]
    3. Apr 23 13:52:43 server postfix/smtpd[9482]: warning: unknown[xx.x.xx.xxx]: SASL NTLM authentication failed: authentication failure
    4. Apr 23 13:52:43 server postfix/smtpd[9482]: disconnect from unknown[xx.x.xx.xxx]

    Hello ;


    As I understand, you are trying to connect from a client. What client are you using? The error message (NTLM...) let me think that your client parameters are wrong...

    Please check your authentication method on your Xerox machine. The password should not be encrypted. Use SSL or StartTLS instead ;)
