I intend to add my Yahoo Mail account as a pop3 account to my old Gmail.
GMail > Settings > Accounts & Import > Add a POP3 mail account you own.
I mentionned my Yahoo account settings but I got the following error message :
Server denied POP3 access for the given username and password. Server returned error: "[AUTH] Access to this service is not permitted."
Any idea ? Why it is not permitted ? is Google & Yahoo not permitting stuffs like that anymore ?
