Introduction
Mozilla Thunderbird is currently the best supported email client in the Physics Department due to its healthy feature set and its cross-platform availability.
The instructions given here are presented in the form of a visual tour through the setup procedure for ussing Thunderbird with the Physics servers. As such, few technical issues are addressed. This is a deliberate choice in order to maximize the value of this document to the least technically savvy users.
To get started, the user must have Thunderbird installed on the system. Installation instructions are outside the subject area of this document.
Phase 1
Upon starting up Thunderbird, if you have no existing accounts, you will see the window below. If you already have an account, click on "Local Folders" in the left panel to get to the same screen.

Now choose "Configure manually". This will result in presentation of the next window.
Now you are at the Server Information page where you choose the type and name of your incoming e-mail server. Choose an IMAP server unless you specifically know that you want a POP server. (We discourage use of POP, although it will be supported for the forseeable future.)
The server name will mail.physics.utoronto.ca.

Please note that the user name must be the part of your e-mail address that precedes the @ sign.
