This guide will take you through the steps to setup your email on an email client called Mozilla Thunderbird. If you do not have Mozilla Thunderbird, you can download it here https://www.mozilla.org/en-US/thunderbird/
Step 1 - Open Mozilla Thunderbird
Once you have installed Mozilla Thunderbird on your computer, you can open it via the Mozilla Thunderbird icon.
Step 2 - Add your email account to Mozilla Thunderbird.
Create a new account by clicking on the "Email" link under the section that reads "Create a new account." See the red arrow below.
Step 3 - Use your existing email
After clicking on "Email" in the previous step, a smaller window will open. Click on the button that reads "Skip this and use my existing email"
Step 4 - Enter your name, email address and password and click continue.
Step 5 - Click on the button that reads "Manual config"
Step 6 - Fill in your email and server settings
Make sure you choose POP3 from the "Incoming" dropdown. Fill in the server hostname and Port for POP3 and SMTP, exactly as received from your hosting provider or your mail settings. Make sure to choose the "SSL/TLS" option under the SSL settings for Incoming mail. Make sure to choose the "STARTTLS" option under the SSL settings for Outgoing mail. Make sure that your username for incoming and outgoing is your full email e.g. firstname.lastname@example.org and not just your name, e.g. test.
Step 7 - Done
Once you have filled in everything on the previous window, click on the button that reads "Done". This will take you to your inbox and you can start sending mail by clicking on the "Write" button.
