I upgraded to smartermail 13x (Free Edition) and trying to create email user using smarter mail web services in asp.net. but getting following error:

 

 

I am using following code:

 

 MailboxAdd("http://172.16.11.71:9998/Services/", "admin", "P@ssw0rd", "Faheemsial", "P@ssw0rd", "smartermaildomain.com", "Faheem", "Sial", False, "faheemsial@smartermaildomain.com", NewSettings, False, 200, False)
