Thank you for your help.
It's definitely something on the mail side of things as you suggest.
If I set the delivery system to CDOSYS and mailserver to localhost with no username/password all is fine. As soon as I save that page though it autofills the username/password with settings from an older install and the mail fails to send.
Trying to figure out how I can now keep those 2 fields from autofilling.
EDIT
OK, so it looks to be a google chrome issue. Firefox saved the settings with blank fields and also activated the account once I pasted the link into it. Chrome still fails to authenticate user though so must handle the data different(??)
Thanks for your suggestions, gave me a good idea on where to start :)
