Read Documents (Mail)

roohishahid

Hello
Im new to rapidminer and I am trying to read my mails from Yahoo throught read document (Mail) operator.
I have given the host name, username and password plus the folder which I want to read, and when I press the play button it says access to this service is not permitted.

Please can someone help me to solve this. I am working to classify mails as spam/normal.

regards

roohi
