@nixCraft Sounds like a good opportunity to Run Your Own Mail Server 😉
I understand that, but this is a suggestion for absolute geeks with a lot of free time to struggle with SpamHaus and other institutions targeting peaceful operation of the server. I would prefer if we all promoted as an alternative to GMail/Outlook/etc. other purely commercial providers like Fastmail et al. instead pushing normals to something where they will eventually and necessarily burn out.
The qualifications for running your own mailserver is not negligible, but it's also well documented in such a way that most competent geeks with a few bucks for a domain-name and VPS could get the fundamentals up and running in a weekend.
A discussion particularly apropos of reading @whitequark's recent thread¹ that crossed my feed, detailing adventures in busting the "setting up a mailserver is hard" myth.
I was running my own server for years. I didn’t give up because of my incompetence (I hope), but because I found that I have better things to do than constantly battling with SpamHause, Google, Microsoft, and others who try to cement the monopoly in the email delivery. I just outsourced that job to Fastmail, and I am very happy with the result.
And yes, her second point is absolutely correct. Let somebody else deal with it. And she still ends with “with everyone but M365.”
I apologise, I didn't want to undermine your feminity. I am sorry.
