Mail cannot verify identify of server error

Nothing is more frustrating for new (or old) Apple users than trying to get the Apple mail client working properly during it’s initial setup. The main thing that we are addressing in this article is the verification of the mail server during setup. The error “Mail can’t verify the identify of the server xxxxxx” often appears when working with the secure (SSL) settings for your mail client (where “xxxxxx” is the name of your server). This tutorial will walk you through the steps needed to make sure that your secure settings will work and your self-signed certificate is saved on your computer so that you don’t have to continually confirm the identity of your mail server.
