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.
