Add an email account with Thunderbird Mail

Start Mozilla Thunderbird and click on the Create a new account link in the local folders section.

Click on the Skip this and use my existing email button.

Enter your name, the email address you wish to add and the email address password.
Tick the Remember password option and then click on the Continue button.

Please note: Thunderbird will now attempt to set up your email. This will fail, but don't worry we will enter the settings manually now.

Please note: You can now choose between using POP3 or IMAP. To find out more about these protocols check out this FAQ.

Enter mail.yourdomain.com as the server hostname.
The port should be set to 993 for IMAP or 995 for POP3.
Now set the SSL to SSL/TLS and the Authentication to Normal password.

Now enter mail.yourdomain.com as the outgoing server hostname. Set the port to 465, the security type as SSL/TLS and the authentication as Normal password. Enter your email address as the username. Once you have entered these settings click on the Done button.

That's it, your now ready to start sending and receiving email straight away
