The problem with this is trust. If you could seamlessly migrate like this, there’s nothing to stop someone faking a long post/comment on their own instance, making them look very legitimate and then migrating that account to a trusted/legitimate instance.
Then using that for spam/selling block chain etc.
People are the reason we can’t have nice things.
How you can have an article talking about the history of email and it not be about Ray Tomlinson, I just don’t know. Wait - now I know: This person looked up the Wikipedia article on the smtp protocol and decided Mr. Postal was the pioneer of email.
The conclusion is completely incorrect, also. About the only correct thing was that reputation is important for email transmission.
No: you can’t just set up an smtp outbound server on your home server and expect the world to trust you. For good reason: we’ve had decades of trojans and viruses taking over home PCs and sending spam. Your ISP declares its “home” IP ranges, and those are immediately not trusted.
That doesn’t mean you need to use a big email hosting provider. If you set up on a business IP range, configure your DNS Correctly with declared mx and spf records, the world will trust you (until you demonstrate that it can’t).
Millions of businesses around the world do this.
My client is spending waaaaaaay more money on Microsoft Online than it ever used to on software licenses. Every single user in the business is costing 🇦🇺$30 per month alone just for their Office suite. That’s before you get to the Azure stuff. Some hosted apps cost over 🇦🇺$1k/month to host in Azure.
Before you go too strongly after Microsoft for charging so much, this is cheaper than what we used to pay for running our own SharePoint, Exchange etc farms as well as the infrastructure required to host websites/database etc. All that has been outsourced to Microsoft Online and saves significant money.
Microsoft is doing very well out of its own cloud fees and can cope with AWS, Google and all the smaller private cloud operations getting some of that action.
