Here’s a brief video that will demonstrate how to set up Apple Mail. This video was recorded from a MacBook using the latest OSX and Apple Mail versions. If you have older software, this may not exactly represent what you’ll see, but it’ll be very similar.
If you’re using a pinehurst.net email address, these are the settings you’ll use:
Incoming Mail Server: mail.pinehurst.net
Port 993 for IMAP
Port 995 for POP3
Outgoing Mail Server: mail.pinehurst.net
Port 587 or 465
