Email in OS X
Open Mail/Preferences. Click the + button at the bottom left to add a new account.
In the window that opens next, select POP as the Account Type. The Account Description identifies the account, so that if you have more than one account you can tell them apart. Under Full Name, write whatever name you want people who receive email from you to see.

Under Incoming Mail Server, enter your domain name (without the www). Your user name will usually be the same as the first part of your email address. If you do not know your user name and password, contact us for help. Click continue.

For Outgoing Mail Server, enter your domain name. Make sure "Use Authentication" is checked, and fill in the same user name and password if it has not been filled in automatically. Click continue.

The next screen will show a summary of your settings. Click continue, then done.
