    Hello,

    Recently we have moved some customers dns zones from our dedicated
    cpanel server to 2 external servers (master/slave ONLY dns server, without any control panel)

    It's a month that some of these customers are calling saying that
    some e-mails are coming back with this error


    This message was created automatically by mail delivery software.

    A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:

    sentto@example.com

    The mail server could not deliver mail to sentto@example.com. The account or domain may not exist, they may be blacklisted, or missing the proper dns entries.

    ------ This is a copy of the message, including all the headers. ------
    ------ The body of the message is 282323 characters long; only the first
    ------ 56496 or so are included here.



    Do you have any idea why this is happening?

    Thanks

    :)
