1. Start the Thunderbird program.

If the Thunderbird program isn’t already running, start it now.

2. Open the “Accounts Settings” window.

In Thunderbird, click Tools, then Account Settings from the menu bar.

The “Account Settings” window appears.

3. Verify the incoming “Server Settings”.

Highlight “Server Settings” in the left-hand column for the e-mail account you would like to verify. The window should look like this:

Review the settings in this window, and make changes where necessary:

• Server Type: IMAP Mail Server (this value cannot be edited)
• Server Name: mail.tigertech.net
• Port: 143
• User Name: address@example.com (must be all lowercase)

In the “Security Settings” section:

• Connection security: STARTTLS
• Authentication method: Normal password

4. Select the “Outgoing Server (SMTP) Settings” window.

First, make sure that “Outgoing Server (SMTP)” is highlighted in the left-hand column (it may be at the bottom of a long list). Then, select your e-mail account in the list in the main part of the window (to the left of the “Add” and “Edit” buttons):

Click the Edit button and the “SMTP Server” window will appear.

5. Verify the “SMTP Server” settings.

The window should look like this:

Verify these settings for outgoing e-mail:

• Description: (your e-mail address)
• Server Name: mail.tigertech.net
• Port: 587

In the “Security and Authentication” section:

• Connection security: STARTTLS
• Authentication method: Normal password
• User Name: (your e-mail address)

(If you are using the older Thunderbird 3.0, then you should check the box labeled Use name and password, set the user name to address@example.com (all lowercase], and select STARTTLS. Do not check “Use secure authentication”.)

Click OK to save the changes. This closes the “SMTP Server” window.

6. Close the “Accounts Settings” window.

When all of the settings are correct, click OK to close the Account Settings window.
