to access your GMail account.
As GMail is an IMAP based email system, all your emails should still be there when you connect to GMail from the Apple Mail app.
I just realised that Entourage was hoarding all my Gmail post, and I couldn't delete anything, as there seems to be some problem. Be that as it may, I hardly use it, preferring Apple Mail and all my online mail boxes. How do I get rid of Entourage, without it deleting all my valid posts in the gmail website?
