    4.2.4 Email Bounce Error

    Reason

    Mailbox Has A Mailing List System Issue: Delayed Message

    The email message has not yet been delivered because the recipient’s email address, which is a mailing list, had trouble forwarding the email message the list members.

    How to fix?

    Check that the recipient’s email address is the correct address for the mailing list you wish to reach. If an error is found, correct it in contacts list or address book for next time. Contact the administrator of the mailing list for help.

    4.2.4 – 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.2.4

    The mailbox is a mailing list address and the mailing list was unable to be expanded. This code may represent a permanent failure or a persistent transient failure.
