Support: Mozilla Thunderbird Email Setup

To begin, please ensure that you have your e-mail address and password handy. Open Mozilla Thunderbird. Please note, the screenshots below were taken with the Windows XP version of Thunderbird. If you are using a different operating system, the visuals may look different but the steps should be the same.

When Thunderbird has finished launching, you should be presented with a menu like this:

Thunderbird Setup - Step 1

Ensure that E-mail Account is selected and press Next. On the following dialog box, enter your name and your e-mail address. Note that the way you enter your name is the way that it will appear in all sent messages.

Thunderbird Setup - Step 2

After pressing Next, you will be asked to select the Server Type as well as to enter the Server Addresses.

Our e-mail system use an IMAP server, so be sure to select that option. Additionally, the addresses for both the incoming and outgoing server are It should look like this:

Thunderbird Setup - Step 3

Next you must enter your e-mail username. Your e-mail username is the same as your full email address. In our case here, the user’s e-mail address is Accordingly, the correct username would be

Thunderbird Setup - Step 4

After pressing Next, you will be asked to enter a descriptive name for your account. This name can be anything you want. It is simply for Thunderbird to help you identify this particular account (though, this is only helpful if your client is set up to deal with multiple accounts).

Thunderbird Setup - Step 5

After this is done, you will be shown a summary screen. Press Next and Thunderbird will register the account. Thunderbird may then automatically present you with a password prompt as it attempts to check your e-mail. Dismiss the prompt by pressing Cancel for the moment. The e-mail account is not completely set up and this will fail.

We still need to configure Thunderbird to use authentication to connect to our servers. This will require a few minor changes. In the Thunderbird menu, find Tools and select Account Settings.

Thunderbird Setup - Step 7

In the account settings dialog, ensure that Server Settings is selected in the left hand sidebar. You will need to configure Thunderbird to authenticate with our mailserver. This can be done selecting TLS, if available from the Security Settings section on the right hand side.

Thunderbird Setup - Step 9

Now, we have to tell Thunderbird where to find your e-mail on our servers. On the same dialog, click the Advanced button in the Server Settings category.

Thunderbird Setup - Step 11

On the new dialog that pops up, enter “INBOX” (without the quotation marks) in the IMAP server directory text field. After that, you can press OK.

Thunderbird Setup - Step 12

As of now, Thunderbird is configured to properly receive e-mail. There are just a few more steps necessary in order to send e-mail. Back in the account settings dialog, click Outgoing Server on the left hand side, and when then the Advanced button on the right hand side.

Thunderbird Setup - Step 13

Finally, change the number in the Port text field from 25 to 8025. Like before, we need to tell Thunderbird to authenticate with our mailserver before anything will work. Ensure that TLS, if available is selected under the Use secure connection: section.

From here, once you confirm your settings by pressing OK, Thunderbird should be completely set up to both send and receive e-mail.
