Hi godspeed27,

I really appreciate your support and patience on this.

I'm currently looking into baltimorestreetmods MERCURY.ini file and noticed some discrepancy between his version and mine. Would you mind sending me your copy too?

If you would like to perform a re-installation on your machine, try it with these conditions this time round:
- Uninstall XAMPP and restart your PC.
- Ensure you have Administrator access to your Windows XP system.
- Disconnect your network cable or network card. Then disable your firewall.
- Install XAMPP into a directory without space (e.g. C:\xampp) but do not start the services.
- Re-start your PC.
- Start up XAMPP Control Panel and then start the Mercury Mail service.
- Open up the Mercury Mail admin interface and check that the default users are there.

Whether the re-installation is successful or not, remember to re-enable your firewall after testing.

Let me know if the above steps work.
