These statements don't seem to be consistent to me. If you transferred your web hosting away from dreamhost but not your mail, then you shouldn't have to make any changes whatsoever.
If you transferred your nameservers away and have deleted all hosting for your domains here, then you're in trouble because by doing so, you've deleted your email here as well.
How are you accessing your email? Are you using webmail, in which case... Hey wait a minute! That thread that patricktan referenced is your crossposted thread (for today) for advice on how to undo the mess that got created when you switched hosting over to your new host!
I'm going to go over and reply in the original thread for actually helping you!
OB on-topic: It's unfortunate that you've had such a bad experience. When you say "1&1 is almost better", at least you're saying that it's not better. Anyway, my experience here has been good, though I'm sure your experience here has unfortunately been less stellar than mine. One general cautionary note for people is to ask for help from their peers here on the forums before they undertake major actions with their hosting account rather than after. Crises are a lot easier to deal with before they've been created.
