- Unable to relay
- Email not working
If an error "Unable to relay" is returned, this is most likely because authentication is not sent to the SMTP server.
- Go to Vista Server settings
- At the email tab set proper authentication (TAC Vista Technical Manual Chapter 3.3 explain this more in detail)
- You may need to consult with the IT department on site
