We need to migrate from iMail to SmarterMail.  We are currently using the iMail database as a poor man's single sign on, same username/password for email and web apps.  We will be moving to a true SSO next year, but in the meantime I need to figure out if I can make my .NET apps use SmarterMail to login and start a session, much like an SSO.

 

Anyone done something even similar?  If my .NET app looks up a username/password via the SM API, then what?
