    Email Bounce Error

    X.4.6 Email Bounce Error [Routing loop detected]

    4.4.6 Email Bounce Error

    Reason

    Network Issue Caused A Mail Loop: Delayed Message

    The email message has not yet been delivered because there was a network issue that caused a routing loop, causing this message to be forwarded over and over.

    How to fix?

    Double check the recipient’s email address to make sure it is correct and attempt to resend the message

    4.4.6- Official definition from ITEF

    For the code that starts from 4.X.X

    A persistent transient failure is one in which the message as sent is valid, but persistence of some temporary condition has caused abandonment or delay of attempts to send the message. If this code accompanies a delivery failure report, sending in the future may be successful.

    For the code that starts from X.4.6

    A routing loop caused the message to be forwarded too many times, either because of incorrect routing tables or a user- forwarding loop. This is useful only as a persistent transient error.

    5.4.6 Email Bounce Error

    Reason

    Network Issue Caused A Mail Loop: Message Not Delivered

    The message could not be delivered because there was a network issue that caused a routing loop, causing this message to be forwarded over and over.

    How to fix?

    Double check the recipient’s email address to make sure it is correct and attempt to resend the message

    5.4.6- Official definition from ITEF

    For the code that starts from 5.X.X

    A permanent failure is one which is not likely to be resolved by resending the message in the current form. Some change to the message or the destination must be made for successful delivery.

    For the code that starts from X.4.6

    A routing loop caused the message to be forwarded too many times, either because of incorrect routing tables or a user- forwarding loop. This is useful only as a persistent transient error.
