On page 3, Giles writes: "Combining the two means Gmail effectively becomes an online backup of every email message in your IMAP account"
Are there any tricks to this, or is it as simple as creating a rule to forward a copy of every message that arrives on the IMAP account to Gmail?
I see that that would work for all new messages, but what about all the existing messages in various subfolders? It would be a bit of a pain to lose existing flags such as "Replied to" or to manually label everything once its copied.
Any cool tips?
