Sometime between February and about a week ago, Dreamhost made it very easy to host your email through gmail.  No more dealing with MX records and the headaches that existed then.  Just go to the web panel, edit the domain you want to set up the gmail account for, and follow 3 simple steps.  This includes creating an account with Google Apps with your desired email account and telling Dreamhost your ready for Gmail.  They do the rest.

It is good to note that the hosted gmail is a bit different than if you have a regular gmail account.  The hosted gmail account is not part of your google account.  This means for other google services like Adsense and Analytics, you’ll need to create a Google account that is separate from email. It’s not too much of a problem, but is a bit annoying.
