Cancellation of the unlimited emails which have not been renewed

If a domain is renewed, while the unlimited emails are not, after 10 days from the expiration date only the 5 standard accounts will be kept active, while the exceeding ones will be at first locked and then after another 5 days finally cancelled.
If before the expiration of the last 5 days, you will not have made the cancellation of the unwanted e-mails, the exceeding accounts will be cancelled at random.
