I've set up my own mail server recently for all my domains. My email is at the bottom of this page https://declassed.art/en/about-me In past I implemented SMTP/POP3 for email over HF radio.
I think this is an irrelevant argument. Why Congress was concerned by foreign interference then? Private companies should have had some social responsibility if they stepped into social area. Or, they should have banned all non-US residents as well. Why Trump only?
Actually, these details aren't interesting to me. A lot was already said about that, no point to say more. I would just like to note that in the global scope, through all my conscious life since 80s, America was great but what's going on nowadays worries me. This reminds me my home country which quickly went through real freedom back to totalitarianism. Maybe, in US things are just slower but the tendency looks the same.
That's a view from my couch, don't take it seriously.
I've been working from home for 15 years and such articles make me laughing. Media simply try to fill the vacuum they are in and their efforts are simply ridiculous.
