Messages can be delivered to a certain domain

    Question

  • Dear all,

    Since this morning it seems that we are not able to send any messages to  a certain domian. We receive such e-mail every time when we are trying to send it:

    Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept
    email from certain senders, or another restriction may be preventing delivery.
    <o:p></o:p>

    The following organization rejected your message: cluster-a.mailcontrol.com.

    Could you please help me to resolve this problem

    Thank you in advance<o:p></o:p>
