Mac OS X: Enabling SSL on E-Mail Clients

This Knowledge Base article will help you understand how to configure different e-mail clients for Mac OS X to use SSL. Most all e-mail clients available today have the ability to use SSL to check your e-mail. Using SSL ensures that no one can intercept your e-mail or password. The following e-mail clients are covered below:

Apple Mail for Mac OS X 10.2

 

Note: To properly use SSL with Mail, you must have OS X version 10.2.3 or later. You can check this by selecting About this Mac... from the Apple menu at the top of your screen. Your copy of OS X 10.2 can be updated as far as 10.2.8 for free by running Software Update, located in the System Preferences. To upgrade to OS X 10.3 or 10.4, contact your site specialist.

 

First, open Mail. You can find Mail in the Dock next to the Finder icon, or in /Applications. See Figure 1.

After Mail opens, go to the Mail menu and select Preferences. See Figure 2.

  • IMAP account: The port will change from 143 to 993. See Figure 7.
