This page explains how to manually 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 for macOS, although other versions are similar. They have been tested and verified with version 60 of Thunderbird.

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 can skip ahead to step 3. Otherwise, click Tools, then Account Settings from the menu bar.

2. Start the "Add Account" wizard

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

3. 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 mailbox you created in your account management control panel.

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

Thunderbird will try to contact our mail server to get the correct settings — let this process continue until it finishes (or fails).

4. Edit your account information

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

Incoming type:IMAP
Incoming Server hostname:mail.tigertech.net
Incoming Port:143
Incoming SSL:STARTTLS
Incoming Authentication:Normal password
Outgoing type:SMTP
Outgoing Server hostname:mail.tigertech.net
Outgoing Port:587
Outgoing SSL:STARTTLS
Outgoing Authentication:Normal password
Username Incoming:address@example.com (all lowercase)
Username Outgoing:address@example.com (all lowercase)

Verify that your settings look like the screen shot below, then click Done:

Doing so will close the "Mail Account Setup" window and return you to the "Account Settings" window. Then click OK to close the "Account Settings" window.

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