What are the enhanced security settings for Apple Mail?

NOTE: These instructions are for Apple Mail version 2 and earlier. If you are using a newer version of Mail, please see the instructions for newer versions.

Enhanced Security users may use Kerberos authentication in addition to TLS to encrypt POP, IMAP, and SMTP authentication. Versions 1.2 and 1.3 both support TLS. You will need to go into "preferences" menu to reconfigure your settings if you used the wizard to set up your account.
