There are two primary ways of accessing your email at CSLab. You can either configure and use a client-side mail reader, such as Outlook or Thunderbird, or you can read and send mail via our webmail server (please see the section below on webmail).
Note that you should avoid using more than one program to access your mail account simultaneously, or unexpected results could occur.
IMAP is a standard protocol which allows you to retrive emails from your email server. SMTP, on the other hand, is a protocol which allows you to send emails.
To send email via CSLab's standard authenticated mail server you must configure your mail client to use TLS. This prevents your access credentials from being sent in the clear. Please use your CSLab login credentials to access our email servers.
The following are standard settings which should be typical for any client.
IMAP server: imap.cs.toronto.edu
SMTP server: smtp.cs.toronto.edu
Connection security: STARTTLS or TLS
Authentication method: Normal Password
Note that some of the above options may not apply to certain clients.
Alternate SMTP server
If you're unable to use authenticated SMTP for some reason, you can use an alternate SMTP server that does not require authentication called mail.cs.toronto.edu.
This server also supports TLS and should be configured with it if possible.
Be advised that you can only use mail.cs.toronto.edu to send email if you are on one of the CS Department's networks. If you wish to use mail.cs.toronto.edu from outside CSLab networks, please first connect using one of our VPN servers.
You may access the Webmail via browsers.
We also provide web apps for downloads on both iOS and Android.

Configure your device to allow "Apps from Unknown Sources" (in Settings > Security), and then download CSWebmail.apk from your device.
iOS 8 (possibly other versions)
Last updated on May 4, 2017.
Latest versions of iOS may not allow this app to install. In this case, accessing webmail.cs through any browser will provide the same functionality.
Download CSWebmail (CSLab login required) from your iOS device, then go to Settings -> General -> Device Management. Under "Enterprise App" click the "University of Toronto" link and then select 'Trust "University of Toronto"'.
