    I have two problems on SBS/Exchange 2003.

    The one site Exchange is set too send email via DNS/SMTP. A user is getting
    a bounce-back error message when sending to a particular domain. The
    bounce-back is as follows:

    You do not have permission to send to this recipient. For assistance,
    contact your system administrator.
    <domain.com 5.7.1 smtp;530 5.7.1 Relaying not allowed.

    All other sending to domains work.

    Another site Exchange is set too send email via smart host (their ISP).
    Users get the following bounce-back message:

    You do not have permission to send to this recipient. For assistance,
    contact your system administrator.
    <domain.com #5.7.1 smtp;550 5.7.1 <domain.com>... Relaying
    denied. Proper authentication required

    Please advise me what to do and if there is something I can do on Exchange
    or is it the recipient's Server?
