How can I create new folders (called "mailboxes" in the email app) to file my emails on the iPad? I get the default sent, drafts, spam, etc folders... But no way to create new ones. I have a couple email accounts. One is a personal email hosted by my isp, that's set up as imap. The other is a yahoo email account, for which I don't even have an imap/pop option when it was set up. I've searched the net for advice on this, and this appears to be a common problem, but the questions always go misunderstood or unanswered. Thanks in advance.
