PKI: Installing and Configuring Thunderbird

1. Installing Mozilla Thunderbird. You can download it from Thunderbird can be used to check both IMAP and POP accounts. If you are going to use Thunderbird to check a POP account a third party extension has to be installed which can be found at You must install the web extension and an optional component, which will be for your specific email account. Currently, this extension only supports Yahoo, Hotmail, Lycos, MailDotCom, Gmail, Libero, and AOL accounts.

Follow the on-screen instructions to install Thunderbird. Upon start up you will be asked if you want to make Thunderbird the default email program, which is not necessary. You must only configure it to use the email account where you will be sending and receiving secure mail. If you are going to use a POP account you must now install the two extensions before you can set up an email account. To see the steps to setup a POP account refer to step 2a.

2. IMAP Email Account Setup. Starting Thunderbird for the first time you should be viewing the Local Folders account, which will allow you to manage all email accounts configured for Thunderbird. To create a new account click the Create new account button.

Then select create an email account.

You will be prompted to enter the name you would like to have appear in the “From” field of any outgoing message and the email address that Thunderbird will use.

To use an IMAP account select IMAP and enter the information for the incoming and outgoing servers.

The remaining set up process requires you to verify certain pieces if information more precisely the user name for your email account and your email address that Thunderbird is being configured to check.

2a. POP Email Account Setup. Install the two extensions and restart Thunderbird to activate them. Before you setup an email account it is best to check that the WebMail extensions are running. This can be done by going to the Extension window for Thunderbird, clicking on the Webmail extension and clicking options. Go to the server menu and make sure the status of both POP and SMTP is running. Also check the Domain menu and checking both the POP and SMTP domains, which should include the domains for the email account Thunderbird will use.

The email account setup is the same as IMAP except when selecting the type of incoming server choose POP and type localhost as the name of the incoming server.

The incoming user name has to be the email address username@domain you are setting up.

The remaining set up process requires you to verify certain pieces if information more precisely that Thunderbird is being configured to check.

3. SMTP Setup. To setup the SMTP server select Local Folders in the Folders menu and select view settings for this account. Select the Outgoing server (SMTP) option. You can change the server name but it should already be setup for your email account along with your username that should be used. If these are not correct make the appropriate changes.
