Gmail Imports Mail and Contacts from Old Email Accounts  Gmail
Imports Mail and Contacts from Old Email AccountsS  Earlier this
year Gmail allowed new users to import contacts and messages
from old email accounts to make switching easier. Today they've
added that feature for everyone, meaning if you've got old email
you'd love to import to Gmail, now you can.  Assuming you're
already logged into your Gmail account, just point your browser
to the Accounts and Import tab of your Gmail settings and click
the Import mail and contacts button to get started. Then just
follow along with the simple import wizard; enter your other
email address, provide the password, and tell Gmail what you
want to import, how you'd like it labeled, and whether or not
you want to keep bringing in new mail for the next 30 days.
You've always been able to import other email into Gmail via POP
fetching, but this simple wizard simplifies and streamlines the
process.  Mail and contact import for everyone [Official Gmail
