Release v21.06.04 adds the option for storing a secondary contact email address for every user.

Since there will likely be a different rate limit for sending email to internal/university addresses vs external/non-university addresses, we must add a new configuration option to the /usr/local/submitty/config/email.json file.

Edit this file and add the following field to the file:

"email_internal_domain": "myuniversity.edu"

Notifications to email addresses that match the specified pattern will be prioritized and sent at a maximum rate of 100 per minute. Notifications to all other email addresses will be sent at a maximum rate of 500 per hour. These rates can be modified by editing the send_email.py script.
