cPanel - Automatic Mail Configuration in Thunderbird

In this article we'll show you how to use automatic settings in your cPanel to easily set up Thunderbird email account on your computer.

We assume you have already created a mailbox in your cPanel. Now you need to log in cPanel and in the Email section click the Accounts link. In the table with created mail accounts Email Accounts find the mail you want to access via Thunderbird and in the Actions column on the same line click the link Connect Devices:

auto config thunderbird

A new window opens, containing two tables with settings for automatic and manual configuration. We are interested in the information in the first table Mail Client Automatic Configuration Scripts. At the bottom of the table next to Mozilla Thunderbird® click the link Auto Config:

auto config thunderbird

A window with instructions will appear:

auto config thunderbird

Click the OK button to close the window.

Nothing more will happen on this page, such as downloading a file ...

Open Thunderbird and in the section Create a new account click Email:

auto config thunderbird

Ignore the next window by clicking the Skip ... button:

auto config thunderbird

  • In the Your name field enter the account name.
  • In the Email address field enter the mail address - in this example 'demobox@demo-icn.com'.
  • Enter the password with which you created the mail in the Password field.

Click the Continue button to continue.

Under the text boxes, the cPanel information, stored on your computer, is loaded and Thunderbird has configured your account without having you to enter server names, ports, security protocol, authentication mode:

auto config thunderbird

Click the Done button to finish the configuration.

The new account has been successfully added to the accounts table:

auto config thunderbird

Let's check what settings are used during the automatic configuration process.

Click on the account name (in this example demobox@demo-icn.com) and in the Accounts section click the link View settings for this account.

In the Account Settings window, open the menu by clicking the arrow next to the account name and click Server Settings:

auto config thunderbird

An IMAP mailbox is configured on the default port 143 and security protocol STARTTLS.

If you click on the last link Outgoing Server (SMTP) in the column under the accounts list and in the table click on the mailbox name, you will see the outgoing server settings - the security protocol is STARTTLS, the connection will use port 587 instead of the default SMTP port 25.

auto config thunderbird

Important: TLS is the successor of SSL and the terms SSL and TLS are used interchangeably unless they refer to a specific version of the protocol. STARTTLS is a protocol that upgrades an existing insecure connection into a secure one using SSL/TLS.

Now let's test whether we can manage our correspondence through Thunderbird. We send a letter to gmail.com:

auto config thunderbird

The letter was successfully received and we also successfully returned a response from gmail.com:

auto config thunderbird

If you want to use a SSL/TLS protocol instead of STARTTLS, you need to make the following changes manually.

In the Account Settings window open Server Settings for the specific mailbox and from the Connection Security drop-down menu select SSL/TLS - automatically the port number will change to 993:

auto config thunderbird

Then click Outgoing Server (SMTP), click the name of the specific mailbox, click the Edit button. In the new window from the Connection Security drop-down menu, select SSL/TLS - automatically the port number will change to 465:

auto config thunderbird

Click the OK button to save the new SMTP settings, click the OK button to save the new IMAP settings and finaly close the Account Settings window.
