    Stale DNS Records


    We are having trouble with a local business emailing us. It started just after we changed our mail filtering service. Here is the bounce back message they get:

    Your message could not be sent.
    A transcript of the attempts to send the message follows.
    The number of attempts made: 1
    Addressed To: [email protected]

    Fri, 05 Sep 2008 15:00:02 -0500
    Failed to send to identified host,
    [email protected]: 147.202.xx.xx (our old mail filtering ip, 553 sorry, mail relay to [email protected] prohibited, please authenticate or set up relaying
    for 69.66.xx.xx (there mail server ip) unknown (#5.7.1)
    --- Message non-deliverable.

    Why is there outbound mail pointing at our old mail filtering ip? We are having no other problems with anyone else. I talked to our ISP support and they said, "They could certainly have stale DNS entries on their end that would cause that, as I do show that IP is not any one of your current MX's." Does this sound like it could be the issue? What do I need to tell the company that's trying to send to us?
