In one line
An official state electronic mailbox used for legally binding communication.
Where you meet it
Self-employed people and companies have one set up automatically, and messages count as delivered whether or not you read them.
The fuller explanation
A data box replaces registered post for dealings with public authorities. A message is legally delivered after ten days even if you never open it, so check it regularly or set up email notifications.
