My IMAP stopped working today. This has happened before when they change the server settings, so I checked the site here for the settings. Now it says, "IMAP is only available to Premium customers." I called their premium customer phone number (found it online), and they confirmed it's only for premium members. They said they recently upgraded their server or something. I don't know when the change was made to a pay only service (never got an email), but it just stopped working for me today.
