  • 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.

About the list that could not be sent

The list of users to whom emails could not be sent is stored in our database and will be given to each user as an Excel list.
Currently, there are five possible cases in which an email could not be sent.

[Step 2]

You can use the same ID/PASS as before.
I think that you have notified us of your ID/PASS separately. Please rest assured that you can use the ID/PASS as it is.

For sending messages

[Countermeasure Case 1]
Send a confirmation request
Since the message is still on the system, please send a message saying "Please log in and check your message" or send the same message again.

[Countermeasure Case 2]
Send a separate email requesting confirmation of the message
Please send a confirmation request email such as "Please confirm your message" by another means (email software), not in the system.

To reset your password

If you do not receive the message, etc., we will ask you to reset the password operation again.

In the case of password reset, the user cannot reset the password and
You may have been contacted by us or by the administrator in some way.

If you have any questions, we would appreciate it if you could tell us that there was a problem with the system on the operator's side and that it is already available.

For the login authentication function

Please inform us of the system restoration. Please use the message function, etc. to inform all system users of the restoration of the login function.
