Create an email address from outside the control panel

Hello.

I'd like to be able to create a new email address / webmail account, from within my site.

The purpose is to allow a 3rd party to add email accounts with out being able to log into my control panel.


Ive tried this code hoping to "trick" the control panel into allowing me to get/post command to it.. with this code;

Set objWinHttp = Server.CreateObject("WinHttp.WinHttpRequest.5.1")
objWinHttp.Open "PUT", "https://my.discountasp.net/login.aspx?ReturnUrl=/email_pop_manager.aspx", False
objWinHttp.Send("txtLogin2=*username*&txtPassword2=*password*&btnLogin=Login&")

Response.Write "Status: " & objWinHttp.Status & " " & objWinHttp.StatusText

But the status returned is 403 Forbidden.


Does anyone have another suggestion on how to create new email addresses from within a web page, rather than the control panel?
