Can I use my current domain name to continue receiving/sending e-mail but with the added features offered by MyMail?
The MyMail Business Accounts permit you to continue using your current domain name for your e-mail. When you set up your business account, you will receive detailed instructions for changing your domain’s MX record to point to MyMail’s e-mail server. This does not affect any other operation of your domain. It simply tells Internet routing services that your e-mail is being hosted on a MyMail server.
