Special Mailboxes

Security and Privacy: Kerberos & TLS

The method you choose to configure your special mailbox has security and privacy implications. Please review the sections below.

Security Warning The procedures described on these web pages do not address privacy issues. Anyone who has access to the computer where you store your mail can read any message in any directory or folder on the hard drive. For more information, visit the network security web pages.

Kerberos is a security system designed to protect access to personal, confidential information on computer networks. When you request access to Kerberos-protected private information, Kerberos verifies that you have entered the correct password for your Network ID (this process is called authentication), and then issues you an electronic ticket, which gives you admission to restricted services.

TLS (also known as SSL v3.1) is another safe, secure way to protect your password when using Eudora. Since you can only have one Kerberos ticket (but can also have one or more TLS sessions active), many special mailbox users will find TLS useful.

• Option A (your special mailbox messages are forwarded automatically to your personal mailbox)

• Option B (you use Personalities to receive special mailbox messages with your personal messages)

• Option C (you set up an independent mailbox for your special mailbox messages AND you want to be able to check both personal and special mailbox messages simultaneously)

• Option D (you set up an independent mailbox for your special mailbox messages BUT you plan to check either only occasionally)

Note: The options refered to here are explained fully on the page on Configuring Your Special Mailbox.

 

If you chose option A (and are having special mailbox messages forwarded to your personal mailbox, all of the special mailbox messages you receive are protected by the same security as your personal messages (you may have chosen Kerberos or TLS).

If you chose option B (and are using personalities to check both personal and special mailbox messages), you can only have one active Kerberos ticket at a time, and we strongly recommend that you use Kerberos for personal messages. This means you will use TLS password authentication for the special mailbox messages.

If you chose option C you have two instances of Eudora running at the same time. You can only have one Kerberos ticket at a time, so you need to make sure that the instance of Eudora you use to check your special mailbox is set up to use TLS.

If you chose option D you have chosen to check for the different kinds of messages (those to you and those for the special mailbox) one at a time. Each time you switch from one mailbox to the other you will need to:

quit the open instance of Eudora
clear your Kerberos ticket (if you are using Kerberos)
open the other instance of Eudora and sign in with the appropriate password
