    Hi. This is the qmail-send program at challah.msrl.com.
    I'm afraid I wasn't able to deliver your message to the following addresses.
    This is a permanent error; I've given up. Sorry it didn't work out.

    <ntbhekcaedkreukdr () aol com>:
    205.188.156.130 does not like recipient.
    Remote host said: 550 MAILBOX NOT FOUND
    Giving up on 205.188.156.130.
