Problem Type: Problem Report
Item: Web+Center 8.0
Resolution:
This can occur if you had open relay configured for your exchange server, and if you went into System Configuration Options and set something and your browser autofill feature went ahead without asking you and modified your SMTP username and password with some previous values in the browser that now turns on SMTP authentication from open relay. Simply edit the SMTP username and password and leave both blank and resave the system configuration options.
