Previouisly, I had asked a question about using Google App Engine with GMail. Now, my question is similar but different: I want to know if I can do the same type of things with other Non-GMail systems such as Yahoo, Xaviermail, etc.... In particular, I want to be able to delete and/or create email folders in those systems. I realize that the instructions may not be the identical coding instructions to do this, but it would be very helpful if all of my email accounts could be centralized into one management application that ran in Google App Engine with separate portions of code for
the different types of accounts.
