Setting Apple Mail to use SMTP Authentication

CIT does not recommend or support Apple Mail for accessing Cornell's central mail system (the "postoffice" servers). CIT supports Mozilla Thunderbird and Eudora, both of which are available as part of Bear Access. CIT strongly encourages using Thunderbird, with Kerberos authentication enabled, for reading your e-mail. CIT also supports two web-based clients, WebMail and the uPortal.Cornell e-mail channel.

You can configure Apple Mail using either Kerberos or SSL authentication

Kerberos:

1. Go to Apple Mail's Mail menu and choose Preferences.
2. Click on the Accounts icon. If you have more than one account, click on the desired account in the list that appears at the left.
3. From the popup menu next to Outgoing Mail Server (SMTP), select Add Server...
4. Set the Outgoing Mail Server to authusersmtp.mail.cornell.edu.
5. Set the Server Port to 25.
6. Make sure the Use Secure Sockets Layer (SSL) check box is NOT checked
7. Use the popup menu to set Authentication to Kerberos Version 5 (GSSAPI). (Note: SSL does NOT currently work with Kerberos. We have notified the developer.)
8. Make sure your User Name is set to your Cornell NetID.
9. Leave the Password field blank.
10. Click OK.
11. Close the Preferences window; click Save when asked if you wish to save your changes.
