Unable to send outgoing mail from WHD

Clicking Save & Email when sending an email from a ticket in WHD returns the following error:

530 5.7.57 SMTP: Client was not authenticated to send anonymous mail during MAIL FROM.


530 5.7.1 Client was not authenticated


All WHD versions


This occurs when the SMTP Relay is not configured correctly.


  1. On the WHD Console, go to Setup > Email > Outgoing Mail Account
  2. Select the account and verify that SMTP Authentication is set to SIMPLE and a valid user name and password are provided.


  • Consult your mail administrator to verify the SMTP Relay Configuration.
  • If you are using Microsoft Office 365, switch to port 25. Refer to Setting Up Outgoing Email Accounts.
  • You can also try to change port to 587 and check the SSL box.
