[imp] Create Spam folder Automatically

[carlos maca]

 I had tryed to create automatically the spam folder, but when someone
reports
 one message as a spam, the spam folder ( that i caonfigure to be called
"spam") do not be created, and a error message appears : TRYCREAT [Mailbox]
DOES NOT EXIST;
 So the only way to me is to create manually the folder "spam", Can Anyone
help me, what i do to create the folder
 automatically when i report the message as a spam!!?
