Eudora on Windows Configuration - Manual Instructions
Note: CETS is phasing out its support of Eudora. If you are trying to decide which software to use, we recommend Thunderbird. If you are currently using Eudora, we recommend you move to Thunderbird; please contact CETS for help with the move.
1. Double-click the Eudora icon on your desktop. Do the following:
- If prompted to enter a password, click "Cancel."
- If prompted to make Eudora your default mail program, click "Yes."
- If you receive the message to update the mailbox list for the IMAP account to "<Dominant>," and this is your first time running Eudora, "No". Otherwise, click "Yes."
2. From the Tools dropdown menu, select "Options."
3. In the Eudora Options screen, click the "Getting Started" icon. Complete the the following fields for "Getting Started:"
- Real name: Type your full name as it will appear on all of your outgoing messages. For example, type Jane Smith.
- Return address: Enter your desired return address. Most users should type USERNAME@seas.upenn.edu (where USERNAME is your Username)
- Mail Server (Incoming): USERNAME.mail.seas.upenn.edu (where USERNAME is your Username)
- Login Name: Type your username.
- SMTP Server (Outgoing): smtp.seas.upenn.edu
Note: If your computer is not connected to the SEAS network, your Internet Service Provider (ISP) may require a different SMTP server setting. If you have trouble sending mail, please check with your ISP for the correct setting.
- Allow Authenication: Make sure this is checked.

4. Click the "Checking Mail" icon to display the settings for this option. Complete the following fields for "Checking Mail:"
- Check for mail every X minute(s): Type the number 6 as the minutes to elapse between Eudora's automatic checks for new email messages.
- Send on check: Ensure this is checked.
- Secure Sockets when Receiving: Select "Required, Alternate Port"
5. Click the "Incoming Mail" icon to display the settings for this option. Complete the following fields for "Incoming Mail:"
- Server configuration: Ensure the IMAP radio box is selected
- IMAP Mailbox Location Prefix: Type ~/Mail/
- Authentication Style: Ensure "Passwords" is selected.

6. Click the "Sending Mail" icon to display the settings for this option. Ensure the following three options are checked:
- Allow authentication
- Immediate send
- Send on check
Ensure Secure Sockets when Sending is set to: "Required, Alternate Port".
7. Click on the "Display" icon to show settings for this option. Ensure that the box for "Automatically download HTML graphics" is unchecked. Disabling automatic downloading of HTML images helps protect your privacy. By automatically downloading images from an email you are communicating with an external server and this verifies that your email address is valid, possibly making you a target for more junk mail.

8. Click OK to save your changes.
* Try sending a test message to yourself.
* Check messages. Eudora will likely give an error regarding the SSL certificate. If this occurs, follow the instructions for updating Eudora SSL certificates.
* If you then do not receive the test message, use webmail to
contact CETS.
