Can anyone recommend an email client that's compatible with iCloud and Linux? I just discovered that Thunderbird doesn't support iCloud (I'm on Ubuntu 13.10). I need to keep the iCloud account for push notifications to my iPhone. The mail app doesn't support push notifications for Gmail, and I'm not interested in using Google's alternative. I feel like I'm stuck in limbo owning both a PC and an iPhone; nothing wants to play nice with anything!
