I don't think so; (though I would set emails to be sent at 8am just to make sure :) The whole issue comes from an implicit expectation that employees read their email after hours because (1) they are likely awake until 11pm-12pm and (2) they always carry their smartphones with email capabilities (3) the task has to be done before the next morning. At 7am, employees are asleep so hopefully this implicit expectation of reading ones email will not transform into morning tyranny. Also, if the emails are received at 7am or 8am, the sender cannot expect the task to be completed before the morning but morning is already here. So managers will organize accordingly and stop feeling that it's OK to send tasks at 10pm to be completed by the morning.
