Configuring Thunderbird to use EE Email Services is relatively straightforward.
Please note that we make use of self-signed SSL certificates to ensure security by
encrypting all email connections. Because these SSL certificates are self-signed
and not issued by a SSL certificate vendor such as Thawte, your email client may
complain about the authenticity of the certificates when you are checking your email
or sending outgoing mail. It is harmless to disregard these messages. Your email
connection is secure despite these harmless warning messages.
Open up your Thunderbird mail client and select your current inbox. From the
Tools drop-down menu, select Account Settings. See Figure One for
an illustration.

Once inside Thunderbird's Account Settings, click on Server Settings
in the left side panel. Make sure that the incoming mail server is mailbox.ee.columbia.edu.
Check the box that says Use secure connection (SSL). If you are using IMAP
(recommended), see Figure Two for an illustration. If you are using POP, see Figure Three for
an illustration.

Last, we must configure the outgoing mail server (SMTP) to authenticate using your
EE user name and password. Select Outgoing Server (SMTP) from the menu beneath
your inbox in the left hand panel. Enter mail.ee.columbia.edu as your
outgoing mail (SMTP) server, and enter 465 for the port number. Select
Use name and password, and enter your user name. Select the button
that says SSL, beneath the text that says Use secure connection.
Click OK to exit and save your settings. You may need to restart Thunderbird
for the settings to take effect.
