Hi Paul,

There are a few things we need to do before we make the switch. 
Here is an outline I have made of what needs to be done:
Change nameserver in goaddy domain manager to: ns17.domaincontrol.com and ns18.domaincontrol.com
In Current mail client (e.g., Thunderbird, Outlook, etc.)
1. Change incoming mail server from mail.frontrangebusiness.com to
2. Set outgoing mail server to smtpout.secureserver.net (using your Godaddy username/password for the outgoing server
(This is done to catch any mail that may or may not be lost.)
3. Create a new mail account in mail client (e.g., Thunderbird, Outlook, etc.) for Godaddy:
Incoming Mail Server will be: pop.secureserver.net
Outgoing Mail Server will be: smtpout.secureserver.net
Everything will take some time to propagate, but you should be good to go from there.
I can drop by you office and go over this with you as well.  Just let me know what time will work best.
