Exchange 2010 user Non-deliverable message

    Question

  • Any help is appreciated. We have a user who is trying to email a vendor who she normally can but now she is getting an NDR message stating:

    The following organization rejected your message: [XXX]. <- other company's IP

    Diagnostic information for administrators:

    Generating server:
    esa1.XXX.iphmx.com  <- our server

    Recipient's email address
    [XXX] <- other company's IP #<[XXX] <- other company's IP #5.0.0 smtp;
    5.3.0 - Other mail system problem 550-'permanent failure for one or more
    recipients (recipients email address:blocked)' (delivery attempts: 0)>
    #SMTP#

    Original message headers:

    X-IronPort-AV:
    E=Sophos;i="4.84,830,1355126400";

    d="xml'?bin'?scan'208,217,72,48?xlsx'208,217,72,48,72,48?rels'208,217,72,48,72,48";a="8561738"

    This NDR is stating that the recipient company has blocked this email address so you will have to contact them to see if they can lift the block or why it was blocked in the first place.

  • This appears on the surface to be a backwards response.

    Given that the email address is at the recipient's server, why would their server block their own email?

    Thus, the response does not make sense on the surface.

    Furthermore, when emailing to a similar failure from say gmail.com, the email makes it to the recipient. Furthering my question in regards to the logic behind this response.  For if Gmail can deliver it, and Exchange cannot, it does not appear to be a recipient's email server problem.
