Apology and countermeasure for the problem of sending e-mail in the learningBOX

Apology and cause

The problem occurred from around 8:00 pm on 2/27/2018 to around 7:00 pm on 2/28/2018. We apologize for any inconvenience this may cause to our users.
As for the cause, our company uses the mail server SES provided by AMAZON, and a case of violation of the SES usage policy occurred, so temporary suspension measures were taken.
The reason for the breach is that a large number of bulk registrations were made with non-existent email addresses, resulting in an extremely high ratio of bounce mail (error mail), which resulted in a warning from AMAZON.
As a temporary measure, we have notified the users who are in conflict not to use the invitation email function.
As a countermeasure in the system function, the e-mail address is currently required, but we are planning to change this to an optional registration form.
We apologize for any inconvenience this may cause. We hope that you will continue to use our services in the future.

Please send a confirmation request email such as "Please confirm your message" by another means (email software), not in the system.
