    Default SMTP authentication with yahoo DSL

    My Zimbra 5.0 install has been working great for a couple of months!

    Now when I send emails out to any external email address I receive this message a while later:

    This is the mail system at host mail.brian-tietz.com.

    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

    : host smtp.sbcglobal.net[207.115.20.40] said: 530 5.7.0
    Authentication required (in reply to MAIL FROM command)




    So now I'm stuck attepting to figure out how to configure zimbra for sbcglobal SMPT authentication... has anyone else had this trouble? And any solutions?

    Thanks,

    ~Brian
