Good point, I don't want to be foolish and make using email worse for me. My area has gotten blackouts, so that can be a problem.
Okay, it is seems that ProtonMail is winning out.
Anyways, I there are so many other cool programs to self-host, so once I get good with those I can tackle email if I think it is still worth trying.
Okay, this looks like a cool solution. I think I have been convinced, given my on level of expertise, I could not pull it off without a huge time sync just to get the scaffolding to understand the tech.
