When you run the Mail program (Mail.app) that comes with OS X for the first time, it will open up a setup window. Type your email address (for example, username@simons-rock.edu) in the Email Address: box. For Incoming Mail Server:, type mail.simons-rock.edu and select IMAP as the Mail Server Type. Your User Account ID is your user name (the stuff before ``@simons-rock.edu'' in your email address). Type mail.simons-rock.edu in the Outgoing (SMTP) Mail Server: text box. Then select Preferences from the Mail menu and click on the Add Account button. Select the Advanced tab and check the Use SSL box. This will establish a secure (encrypted) session for receiving your email. Finally, we recommend that you include a Show Headers icon in your toolbar for ease of reporting spam. Go to the View menu and select Customize Toolbar. Drag the Show Headers icon up to the toolbar and click Done.
