Setting Up Email Account with Thunderbird

Mozilla Thunderbird is a free, third-party email client that offers easy setup and customization with a user-friendly interface. This article will explain the general setup of Mozilla Thunderbird.

Mozilla Thunderbird is available for download at the following link:


Before setting up Mozilla Thunderbird, please ensure the following items have been done.

How to set up Thunderbird

Here is a video tutorial in setting up an email account with Thunderbird:

Here are the steps that you can also follow:

  1. Open the Thunderbird application.
  2. Go to Tools and click on Accounts Settings.
  3. Click on the Account Actions button.
  4. Select Add Mail Account.
  5. Click Continue.
  6. Enter your name and email address in the input boxes. This does NOT have to be your [email protected]. Email addresses such as [email protected], [email protected], etc., are acceptable as long as they are set up in the hosting control panel.
  7. Click Continue.

Thunderbird will try to determine your account settings based on the domain portion of your email address (that is, the portion after the "@" symbol). You can either allow the default lookup or click the Stop button to proceed with the Manual Configuration ⤵.

Using the Auto-Configuration Option - When using the auto-configuration for account set up, choose whether you would like to use IMAP or POP connections. Click Done when completed.

Thunderbird will take care of the rest!

Thunderbird 78

When setting up Thunderbird 78, follow Steps 1 to 4 ⤴. Then, continue with the steps below:

  1. Click on Configure Manually.
  2. Fill in the following information:
    • Protocol: IMAP or POP (Refer to the description below Manual Configuration Options)
    • Server: Type in your mail server (mail.domain.com)
    • Port: You can put 25 or 26 in Outgoing. If your isp is blocking port 25, which many do to prevent spam, then choose 26.
    • Authentication: Choose a normal password.
    • Username: This is your full email address. Make sure you have created this account in cPanel first.
  3. Click Re-test.
  4. Click Done.

Using the manual configuration options

(Continuation of the steps above.)

  1. Click the Stop button to stop the auto-configuration feature.
  2. Edit the Server names and ports to the exact settings desired.
  3. Select either POP or IMAP - both are supported on our servers. If you plan on setting up your mail on many computers, use IMAP.
    • POP: Downloads emails to your local computer and removes the copy from the server.
      • Good for preventing your inbox from becoming slow or full
      • Allows you to view emails offline.
      • Since the emails are downloaded and removed from the server, you cannot receive emails on other computers you may have.
    • IMAP: Accesses emails when viewing them, always keeping a copy on the server.
      • Suitable for accessing emails from many computers (from the office to your home)
      • Requires that you have an internet connection when viewing emails
  4. Click the Manual Configuration button.
  5. In the left pane, select Outgoing Server (SMTP) from the bottom of the list.
  6. Now fill in the following information in the designated fields:
    • Description: Enter your email address.
    • Server Name: Type in your mail server (mail.example.com).
    • Port: You can put 25 or 26. If your isp is blocking port 25, which many do to prevent spam, then choose 26.
    • Make sure the checkbox is checked for Username and password.
    • User Name: Type in your full email address. Again, make sure you have created this account in cPanel.
    • Make sure that TLS, if available, is selected.
  7. Click OK to finish.


Final settings check

To make edits to any other entries to your account once created, select the email account and do the following:

  1. Select Outgoing Server (SMTP) from the bottom of the list.

  2. Select SMTP from the dropdown list.

Everything listed can be altered and extended as necessary.

  1. Also, click on Server Settings listed under the new account.

The entries list must match your hosting provider.

Once everything is exact and saved, users will be able to send and receive emails via Thunderbird.
