Dale,
Further testing reveals that we need to setup the below
mail.smtp.starttls.enable=true
mail.smtp.starttls.required=true
mail.smtp.ssl.trust=FQDN
We found 2 issues.
First issue - user emails not working.
Now the AUTH LOGIN 2.7.0 Authentication successful
But mail from user to the same user (internally) not working.
Reason:
authentication was provided by the admin user and normal user can't send email as admin user
DEBUG SMTP: got response code 550, with response: 550 5.7.1 Client does not have permissions to send as this sender
Second issue - system emails not working like queue problems, site not responding etc
Reason: In this case, tool has not reached the login steps.
DEBUG SMTP: got response code 530, with response: 530 5.7.1 Client was not authenticated
Is TLS supported with Windchill 10.1 M030?
