SmarterMail 4 on IIS with Plesk

[preluderd]

I have a default SmarterMail setup with Plesk and it works fine when I use the address http://www.domain.com:9998 when I go to http://webmail.domain.com SmarterMail loads however authentication fails. If I use the correct username/password it just reloads the page. If I use an incorrect username/password it will tell me the username/password is incorrect. Anyone have any ideas?
