Thunderbird

Creating an IMAP account in Thunderbird:

Start Thunderbird for the first time and the Account wizard should appear.
Select "Email Account" and click on "Next"
On the next page, fill in the "Your Name:" text box with the name you would like to appear in the "From" filed of your outgoing messages. Then enter in your CSDOM email address where appropriate.
On the "Account Wizard" page make sure to select IMAP and set the Incoming and Outgoing server to mail.cs.virginia.edu and select "Next".
Now ensure that "Incoming User Name" is the same as your unix account userID and click "Next".
Enter in an "Account Name" and then click on "Next".

Review your information and once you are sure it is correct, select "Finish".

In the mail client go to "Tools" -"Account Settings"
Under the "Server Settings" option, choose "SSL" under the Security Settings
Under "Outgoing Server (SMTP)", check "SSL" under the "Use Secure Connection"
Click "Okay" and exit.>
Now select "Get Messages" to download your mail.
The first time you connect to the mail server you will see a warning message saying "Website Certified by an Unknown Authority". This message is displayed as the CS department certificate is self-signed, which is fine.

To make this message go away, select the "Accept this certificate permanently".
