I have an bluehost's account email and recently I have installed Ubuntu 11.10. Now I want to setup my account in Evolution or Thunderbird but I can't it. I don't know if problem is about the settings or client email can't connect with the server IMAP.
You might just either call them, or send a ticket. But, I did a search for you on their website helpdesk and here is the link that shows all about thunderbird.
