I have absolutely no idea of what that says... but you should know that you're not the one that gets to define what is or isn't spam.
If you're saying you sent out a ton of email to members that agreed to receive mail from you, and just about all of them reported it as spam, I'd be willing to bet it was spam.
If you're saying some sort of script at DH automatically blocked you because of what you were sending out, then I'm sure DH would check it out and undo it if it's a mistake.
Otherwise, there has to be more to it than simply emailing your members. There are plenty of people here with mailing lists, forums, etc... that don't get shut down for spam.
If it's something legit, clear it up with Dreamhost. In any case, there's nothing anyone here can do--we're just customers. If you play dumb or hide anything while dealing with them, I wouldn't count on them replying or giving you access to anything.
Also, 200 members isn't a huge community. If this takedown was based on complaints, I'd guess that most of them complained and you just need to move on.
If that is the case, I wouldn't email any members at your new host until you have a better idea of what people want to receive mail about, or it will happen again. Example: If you run a forum about cooking & recipes, your member emails probably shouldn't have affiliate links to "Win a free iPod!" offers.
I'd also add that if you're blaming this on someone else that you gave access to your account, then it's still your responsibility. If you're saying it is spam, but your admin did it, that doesn't really help change anything.
