    Question Help.. Bounce as "loops back to myself" if sent to unknown user

    Hi,
    first of all I am running Zimbra 7.2.4 Open Source Edition.

    all other thing is running fine except for the when local or outside user send e-mail to non exist user, they will get the bounce message like this:

    This is the mail system at host mail2.mydomain.org.

    I'm sorry to have to inform you that your message could not
    be delivered to one or more recipients. It's attached below.

    For further assistance, please send mail to postmaster.

    If you do so, please include this problem report. You can
    delete your own text from the attached returned message.

    The mail system

    <bob@mydomain.org>: mail for mail.mydomain.org loops back to myself

    ...why is it the bounce doesn't tell the user that the e-mail account is not exist or unknown user?
    any config that I need to know to fix this?

    by the way this is output from postconf as user zimbra :
