NDR #5.0.0 smtp; 550-Please turn on SMTP Authentication in your mail client

  • 1.  NDR #5.0.0 smtp; 550-Please turn on SMTP Authentication in your mail client

    Posted Mar 31, 2020 02:06 PM
    Trying to send an email through messagelabs sender to proofpoint recipient and receiving the following error, which has been deidentified.  Can anyone tell me which mail service is at fault and what specifically needs to be changed to get this to go through?  Proofpoint has no record of being contacted by the messagelabs server.

    Delivery has failed to these recipients or groups:
    User@domain.com
    A problem occurred during the delivery of this message to this e-mail address. Try sending this message again. If the problem continues, please contact your helpdesk.
