I'm a little perplexed -- I'm trying to configure AquaMail on a new tablet and of the choices I select "other mail" [I'm using dreamhost]. It asks me for my user/password and when I hit "next" I get an instant "error connecting" for both IMAP and SM TP. Where/how does it get the host to use? How can I set it [e.g. imap.dreamhost.com]
