    Hi Guys,

    Why is it that whenever I send emails using yahoo/gmail from a
    connection that uses dynamic ip address to the company's smtp server,
    postfix blocks them and say it comes from a dynamic ip address using
    sbl-xbl, and whenever I send emails using the same yahoo/gmail account
    in the office that has a public static ip address, the mail is
    received.

    TIA
