I have been working on for days for this problem. I have two buttons. One button is to send mails from Gmail to Gmail, another for Gmail to Hotmail.
I can send mails from my Gmail account to another Gmail account but something goes wrong while sending from my Gmail account to Hotmail.
..mailbox unavailable server..... server response 5.7.3 Requested action aborted; user not authenticated
After five days I am about to give up. I have checked releated threads on SO
