i downloaded POP and IMAP Troubleshooter from
http://mail.google.com/support/bin/answer.py?hl=en&answer=141763, then ran it from a XP and it showed all communication channels were OK.
then i found the correct POP and SMTP servers should be "pop.gmail.com" and "smtp.gmail.com", NOT "pop.google.com" and "smtp.google.com" that I used initially!
after changed the server settings, i instantly received a request to confirm Google's certificate, then i saw the emails in my Gmail box. :)
but it still have a few issues, i can only see the Inbox, no view to see other emails filtered by Gmail Labels; and i can't see the emails in my Sent Box... i set IMAP for this account on E72.
any clue?
thanks,
bbao
