> Hasn't it been common knowledge for over a decade now that self-hosting email isn't "allowed" in practical terms?

Well I've been self hosting my emails for 10 years now, and my emails still go through. I'm sure there must be cases where you face issues, but not my in my personal experience.

Only thing I've seen once or twice are websites with "validation" rules like /.@(gmail|hotmail|yahoo)./

I have also been self-hosting my email for almost 20 years.

Until a few years ago I never had any problems, but during the last 3-4 years I had sporadic problems with messages that either were not delivered or they were delivered with a very large delay, e.g. a day, or they were delivered only if I resent them 3 or 4 times, at some of the large providers, like Gmail.

It still works fine most of the time, but when problems happen they are annoying because there is no way to know that something happened, unless I have an alternative way to ask the recipient, e.g. by phone.

In any case, now I always check that at least the final destination e-mail server has accepted the message, which should have been enough to guarantee the delivery, according to standards, but nonetheless this is not true any more.

Yep. For important emails, I tail the exim mainlog. But in six sigma cases, it just works or I get to know that my mails were not delivered days later.
