Thanks Michele!
No I'm just using Apple Mail so the usual folders will do (Inbox, Drafts, Sent, Trash). I have a Spam folder which my Anti-Spam App installed so not sure how that will sync? Also there's a Notes folder in Apple Mail. Will I need to add these to the servers to get them to sync (not too worried about the Notes folder)?
I tried switching my existing email to IMAP in Apple Mail (EDIT: found out this can't be done... you need to set-up a new IMAP account an drag and drop the emails into the respective folders) but it then tried to upload almost 2000 messages to the server folders (I think that's what it was doing anyway?) so I panicked and hit cancel
I'd like to keep all my existing messages in the Mail app but I don't want my iPhone to start downloading 2000 messages as soon as I set-up the IMAP account on that.
Any tips?
