I think they're just not being an open relay. The SMTP error message
was :

  jose@???
      SMTP error from remote mailer after end of data:
      host smtp.katamail.ksmail.it [194.153.172.230]:
      553 Authentication is required to send mail as
      <maria@???>


I think the MLM is trying to masquerade itself as the original poster,
and thus is being denied. The MLM should change the envelope sender
to refer to itself rather than try and leave the original intact.
