Thunderbird is an easy to use email application that runs on Windows, Mac OS and Linux. Configuring Thunderbird to access your standard mailbox will only take a couple of minutes to complete.
You can connect to your mailbox using either the POP3 or IMAP protocols. As a rule of thumb it is better to use POP3 if only one computer accesses your mailbox, while it is better to use IMAP if you have a number of computers that will access your mailbox
We have separate articles that explain the process of setting up your Advanced or Exchange mailbox.
Step 1
Open Thunderbird
Step 2
If you don’t have any other mailboxes set up in Thunderbird, the Account Wizard will open
If the wizard does not open automatically, click Account Settings in the Tools menu.
Step 3
Click the Add Account button.
Step 4
Select the Email account radio button and then click Next.
Step 5
Enter your name in the Your Name text-box. This is what most people will see when you send them an email. Enter your email address in the Email Address text-box and then click the Next button.
Step 6
Depending on the type of connection you prefer, check POP or IMAP as the incoming server type.
Step 7
- Incoming server: Enter mail.yourdomain.com (replacing yourdomain.com with your domain name)
- Outgoing Server: Enter the outgoing SMTP server name supplied by your ISP.
Step 8
Enter your full email address in the Incoming User Name text box.
Enter the SMTP username provided by your ISP in the Outgoing User Name text box and then click Next.
Step 9
Use the Account Name text-box to enter the name you want to use to identify this account. This name will only be visible to you. Click Next. 
Step 10
Confirm the details you have entered. Click Finish and then click OK to close the Account Settings window.
Thunderbird is now set up to receive emails from your Standard mailbox, and send using your ISP’s outgoing mail server.
