The problem here is because my old host accepted email with either the www. or without. I never missed emails due to that alone. ALso, that doesn't change all the webrings, lists, websites, messageboards, profiles, business accounts, online accounts, etc, all which DO have that, and frankly, there is NO way I could possibly retrace my steps after four very busy years with my domain.
I've never encountered a host that actually saw a difference between an email address that had the www or didn't.
Going back isn't an option - I rather had felt that Dreamhost would have a way to deal with such things, and I would get a solid no nonsense solution, rather than a "this might work."
Or at least a solid answer, one way or the other. Yes we can do this, no we cannot do this, yanno, that kind of thing.
Thanks anyway though.
