Don't deliver mail to a London recipient if it is midnight in London. If it's noon on a weekday for another recipient, go ahead and deliver it to them. Also, there would be no need to have restrictions on sending -- email is store-and-forward already. Send all you want, it will get delivered when the receiving party is available. These used to be the default expectations around email: your recipient will see it during business hours, when they next dial in. Broadband and always-on internet creeped up without us really examining this, so Outlook is now just a chat client with a weird UI.
