I though BoxBuddy was installed by default on uBlue distros? It works quite well, too.
Maybe Hotmail, I couldn't say about freemail domains, but I get dmarc reports for recipients on Office 365 hosted domains all the time and have for years. They were one of the earliest adopters, since I've had a dmarc policy for my domains for over a decade.
The point is that if an SMTP server is respecting RFC7208 then you don't get those bounces if you have the records. Which is most SMTP servers now.
SPF
DKIM
Dmarc
You might want to learn about those as well.
Well, when I moved to the AIO, the documentation was plain wrong on several points. I submitted a bunch of changes that I had to do to make it work and they worked those changes in for the most part. Now it seems pretty workable, as a friend of mine used it to set his instance up and said it seemed to go fairly smoothly.
Jesus, that escalated quickly...
And here I am having used it for a decade and perfectly happy. I try other ones like Owncloud every once in a while and find them lacking. It was slow once upon a time but if you changed to postgres and used redis, it improved immensely. Today it's quite fast and the sync has been working great for a long time.
Use docker-compose with the AIO and it'll be a lot easier to manage. There's example compose files in the github repo.
Well, it was kind of a joke, but maybe not.
