Setting Mulberry to use SMTP Authentication

CIT does not recommend or support Mulberry 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 eMail channel.

However, if you elect to use Mulberry you will need to use Kerberos or enable TLS support to encrypt your password when it is sent to the server for authentication.

To use Mulberry 3.x with Kerberos, you must run one of the following installers: Bear Access, uPortal.Cornell infrastructure, or the standalone Kerberos installer. Unless you do this first, the Kerberos option will not be available when you launch Mulberry.

To configure Mulberry to use Kerberos with an SMTP connection:

1. Go to Mulberry's File menu and choose Preferences.
2. Click on the radio button next to Advanced.
3. In the Accounts tab select SMTP from the dropdown list.
4. Enter authusersmtp.mail.cornell.edu in the Server field.
5. In the Authenticate section set method to GSSAPI
6. Click OK to close the Preferences window.

To configure Mulberry to use TLS with an SMTP connection:

1. Go to Mulberry's File menu and choose Preferences.
2. Click on the radio button next to Advanced.
3. In the Accounts tab select SMTP from the dropdown list.
4. Enter authusersmtp.mail.cornell.edu in the Server field.
5. In the Authenticate section set method to Plain Text
6. If you have a Secure dropdown box, select STARTTLS-TLSv1. If you do not have a Secure dropdown box, you should update to a newer version of Mulberry.
7. Click OK to close the Preferences window.
