Problem: Configuring Mozilla
Thunderbird 2 on the Mac to use Zimbra for Faculty and Staff
Solution:
WARNING: The TSO Help Desk supports only the configuration of Mozilla Thunderbird for the specific purpose of connecting to GA Tech servers. For problems or questions concerning its use, please consult the application's Help menu or the Thunderbird Help web site. You should also try MozillaZine's Thunderbird forums.
Thunderbird is an application for email and newsgroups from the Mozilla Foundation.
1. If you are running Mozilla Thunderbird for the first time, you will be taken to the Account Wizard automatically (skip to Step 2). If not, you can manually launch the wizard from the menu.
- Tools > Account Settings...
- From there, click Add Account...
- On the first screen, choose E-mail account. Click Continue.

- Enter your name and GT email address. Click Continue.
- Set the type of server to IMAP. The incoming server should be mail.gatech.edu and the outgoing server should be mail.gatech.edu. Click Continue.
- Enter your GT Account username in the Incoming User Name box. Click Continue.

- Enter the name of your choosing for this mail account. In this example, we use Zimbra. Click Continue.

- On the last screen, review the settings. If everything appears correct, click Done.
- You will now need to change a couple of settings before you will be able to connect. You can get to the settings via the menu.
· Tools > Account Settings...
- Choose Server Settings
under the Zimbra account on the
left. Click the SSL radio button. Check the Check for new messages at startup checkbox.
- This step is optional, but recommended. Choose Composition & Addressing under the Zimbra account. Uncheck the box labeled Compose messages in HTML format.

- Choose Outgoing Server (SMTP) on the left. Click Edit on the right. Check the box labeled Use name and password. Your user name should already be filled out in the User Name field; if not, add it. Change the setting under Use secure connection to TLS.
NOTE: Some ISPs
do not allow connections to computers outside of their network on port 25. See
the troubleshooting information below for possible alternatives.
- Click OK twice.
- Click Zimbra in the left pane. Click Read messages in the main pane.
