Apology and countermeasure for the problem of sending e-mail in the learningBOX
Apology and Cause
The problem occurred from about 20:00 on 2/27/2018 to 19:00 on 2/28/2018. We apologize for any inconvenience this may have caused to our users.
The cause of the problem is that we use the mail server SES provided by AMAZON, and due to a case of violation of the SES usage policy, a temporary suspension measure was taken.
The reason for the violation was that a large number of batch registrations of users with nonexistent e-mail addresses occurred, resulting in an extremely high percentage of bounce mails (error mails), and AMAZON received a warning from AMAZON.
As a temporary measure, we have notified the affected users not to use the e-mail invitation function.
As a countermeasure in the system function, we are planning to change the current requirement of an e-mail address to allow users to register their e-mail address on a voluntary basis.
We apologize for any inconvenience this may cause. We hope you will continue to use our system as usual.
