This page explains how to set up the free Mozilla Thunderbird email program to send and receive email for a mailbox that you've created.

You can download Thunderbird for Windows, Mac OS X, or Linux from the Mozilla Thunderbird site.

Before you continue, you should enter your email address (the address you want to set up in Thunderbird) in the box above. Entering your email address makes sure that the instructions below are correct.

These instructions and screen shots are taken from Thunderbird 6 for Windows, although other versions are similar.

Setting up Thunderbird

Follow the instructions below to set up Thunderbird.

1. Start the Thunderbird program

Start Thunderbird. If no mail accounts are already defined, the "Mail Account Setup" window will automatically open, and you should skip to step 5 below. Otherwise, click Tools, then Account Settings from the menu bar.

If you've already added a different email address that uses "" as the outgoing server, you can skip ahead to step 4. Otherwise, complete steps 2 and 3 to specify the outgoing SMTP server (or to correct its settings).

2. The "Account Settings" window appears

First, make sure that "Outgoing Server (SMTP)" is highlighted in the left column (it may be at the bottom of a long list). If no SMTP server has yet been defined, then click the Add button on the right side to create a new outgoing server. If you want to correct the settings for an existing SMTP server, then select it in the list in the main part of the window and click the Edit button.

3. The "SMTP Server" window appears

Enter these settings for outgoing email messages:

  • Description: (your email address)
  • Server Name:
  • Port: 587

In the "Security and Authentication" section:

  • Connection security: STARTTLS.
  • Authentication method: Normal password.
  • User Name: (your email address)

The window should look like this:

(If you are using Thunderbird 3.0, then you should check the box labeled Use name and password, set the user name to (all lowercase), and select STARTTLS. Do not check "Use secure authentication".)

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

4. Create a new incoming mail account

Click Account Actions and then Add Mail Account (in the bottom left of the "Account Settings" window) to create a new email account.

5. Enter your name and login details

"Your Name" is the name that other people will see when you send them email. It should usually be your real name, such as John Smith or Joan of Arc. Enter the name you want other people to see when you send them email.

Then type your email address. The address must be the email address of the POP mailbox you created in your account management control panel.

Enter the password for the email account and check Remember password, then click Continue.

Thunderbird will try to automatically detect the incoming server information — let this process continue until it finishes.

6. Review your account information

Click Manual config. Review the settings in this window, and make changes where necessary:

  • Make sure that the "Incoming" row is set to: IMAPmail.tigertech.net143STARTTLSNormal password
    (If you prefer to use POP instead of IMAP, you can use "POP3 — — 110 — STARTTLS — Autodetect" instead)
  • Change the "Outgoing" row to: SMTPmail.tigertech.net587STARTTLSNormal password.
    (If you already have another entry for in the "Outgoing" list, you can simply choose that instead.)
  • Change "Username" to your full email address (all lowercase):

Verify that your settings look like the screen shot below, then click Advanced config (instead of clicking "Create Account"). Doing so will close the "Mail Account Setup" window and return you to the "Account Settings" window. Click OK to close the "Account Settings" window.

Setup is complete

You're finished! Try sending yourself a test email message to make sure it works.
