I have configured password recovery with IS 5.2.0 using email notifications. The issue is,
Even though we have provide invalid email settings(invalid host, invalid/empty port) under axis.xml file, Identity server didn't prompt any error message and the mail also not getting sent from the mail server.
Instead of giving an error message, Identity server provides below log,
IS should provide an error message if the email settings are incorrect or failed to sent the mail.
