  • You will now be asked to set up your identity. The "Your Name" field can be anything you choose, and will be displayed at the recipient's end. In this example, we have used Thunderbird Test Account, which will mean the recipient of each email will see it has been sent from "Thunderbird Test Account". The "Email Address" field will need to be filled in using the email address you are currently setting up


  • The next step will ask you to enter information regarding the incoming and outgoing mail servers. These settings are outlined below:

    • POP/IMAP: Information regarding the difference between these two protocols can be found at this MyHelp article
    • Incoming Server: This will need to be set to
    • Outgoing Server: If you are connected to the internet via a Westnet connection, this will need to be set to If you are connecting to the internet via another provider, you will need to use the outgoing mail server given to you by that provider. If you are unsure of this setting, you will need to obtain this information from the provider you are connected to
    • Use Global Inbox (store mail in Local Folders): If you are setting up more than one email account, Local Folders allow you to store all your incoming email in one folder. If you would prefer to seperate your email accounts, simply remove the tick from this option
  • Once you have entered these details, click Next to proceed
  • You will now need to enter the incoming username for your email account. Please note, this is not your main Westnet username, but simply the first part of your email address, prior to the @ symbol. In this example, the email address we are using is so the incoming username will be mozilla.thunderbird. This should already be entered for you, so no changes should be required


  • After clicking Next, you will need to enter a name for your email account. You can use any name you like to identify this email account. The default
