Gmail now has IMAP
A while back I wrote some instructions on how to get Gmail (which then only supported POP) to work properly with Apple’s Mail client. Well, Google have now added IMAP support to Gmail, so a lot of the jiggery-pokery necessary to get that to work is now unnecessary. The instructions still work, but IMAP is a much more straightforward way to access Gmail.
Gmail posted good instructions on how to get it work in Apple Mail here.
