How to Configure Mail 2.1.x for IMAP Email, Kerberos Authentication, and Penn Online Directory (Mac OS 10.4.x)

Apple's Mail is among several email clients in use on campus, and is not supported by all schools and units. Please refer to the document Email Specifications by School or speak with your Local Support Provider (LSP) to find out which email client is recommended for your use.

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

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.

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.
