If everyone runs their computer 24/7 or if you are willing to live with the limitation that somebody can only write you an email when your computer is turned on, then you can do that.
And of course if everyone runs their computer 24/7 and exposes it to the internet, then we are back where we started, everyone runs, maintains, patches, and secures their own servers. Which nobody wants to do even if they were capable to do so, which they are not.
- elevation 3y agoEmail already supports delivery to destinations which are intermittently connected. The legacy MTA behavior is to retry automatically every few hours for several days, with failure resulting in a notification to the sender. Operators have adjusted the behavior over the years to support grey-listing so the retry period and interval are both shorter -- but still in use! While communication between two hosts which are rarely simultaneously connected is best facilitated by a third party, some tweaks to your MTA's the delivery retry interval and period could enable reliable communications between email users who are connected simultaneously on a regular basis.
