Both my work and home ISP's have converted their DNS records (ignore it if it's over your head) so that if I type BrentButler.com in my address bar, I get the new server. Using that as an assumption, I believe it's all done.
You can even TraceRT brentbutler.com and get brentbutler.com as the hostname. To do this, follow these instructions:
Go to your Start menu and click "Run.."
Type "cmd"
A window will come up. In that window, type "TraceRT www.brentbutler.com" and hit enter
It will then trace it's path that it takes to get to my site and the last server you should see there will say brentbutler.com.
I've also got a spam filter up and running (finally). I probably got 120-140 spam e-mails since I moved my e-mail box to this new server. This filter has already caught about 15-20 messages since it started running this morning.
