Remote host said: 550-Please turn on SMTP Authentication in your mail client, or login to the 550-IMAP/POP3 server before sending your message. Asp.reflexion.net is not permitted to relay through this server without 550 authentication. 

To resolve, please log in to the DNS control panel for the customer. Click the Email Routing/MX Record option and make sure it is set to Local Mail Exchanger.
