Email failed to sent to ONE external domain RRS feed

  • Question

  • Hi,

    Just 2 month ago, we upgrade from Exch2003 to Exch2010. All was working fine.

    Then, it was reported that from Internal, we can't send email to this ONE particular domain.

    Below is the bounce back

    -----------

    soonhoe@abc.123
    The server has tried to deliver this message, without success, and has stopped trying. Please try sending this message again. If the problem continues, contact your helpdesk.
