How to Configure Apple Mail 3.6.x for IMAP Email and Kerberos Authentication (Mac OS 10.5.x)

This document provides instructions for configuring Apple Mail for IMAP email. In IMAP mode, your email remains on the server allowing you to access your mail from any computer.

Apple's Mail is one of several email clients in use on campus and is not supported by all Schools and Centers. For the recommended email client you should use, see Email Specifications by School or ask your Local Support Provider (LSP).

Note: Most Mac OS users on campus choose either Thunderbird or Mail as an email client. You do not need to configure both for email. The instructions in this section are for configuring Mail as an IMAP email client. Instructions for configuring Thunderbird are in Configuring Thunderbird 2.0.0.x for IMAP Email.

Mail is already installed in the Applications folder on your hard drive, and an alias for the application is placed by default in dock.

Important: Configuring Apple Mail and Address Book with the below instructions requires you to enter your actual PennKey password. This information is stored on your hard drive with 128-bit encryption. If you are uncomfortable doing this, consider using another email client such as Thunderbird.
