I set  below in .emacs.

 ;; If you use the default mail user agent.
(setq send-mail-function 'smtpmail-send-it)

;; Send mail using SMTP via mail.example.org.
(setq smtpmail-smtp-server "smtp.gmail.com")

;; Send mail using SMTP on the mail submission port 587.
(setq smtpmail-smtp-service 587)

;; Authenticate using this username and password against my server.
(setq smtpmail-auth-credentials
      '(("smtp.gmail.com" 587 "xxx@gmail.com" "xxx")))

But send fail. it says: smtpmail-send-it: Sending failed; SMTP protocol
error

What else do I need to do ?

Thanks
