We are facing an issue when we try to send Trend Charts to email, as per the error message we understand that Authentication is failing because of some exception.
And below are the few checks performed like the settings in mail.properties and it seems all configurations are good, except mail.domain property which is showing as empty.
Below are the error Details and screenshot fyi:
DPA was unable to send the message due to the following error:
com.confio.iwc.mail.exceptions.MailException: Error sending mail: org.springframework.mail.MailAuthenticationException: Authentication failed; nested exception is javax.mail.AuthenticationFailedException: No authentication mechanisms supported by both server and client.
Check the DPA Web Client logs for more details.
Let me know if you need any more information to debug the issue.
