Who whitelists email domains? Do they explain why?

[Semaphor]

I think Aliexpress does it, at least I wasn’t able to use my domain and had to use my old gmail account.

All I got was "not a valid email" or something like that.

The most recent incident I remember was with a debrid service. I opened a ticket with their support and was told that the point of the policy was to combat abuse of their service. Not entirely sure why a paid service that accepts cryptocurrencies would care about email addresses.

I think yandex does. Or at least they didn't allow one person send emails to me. "invalid address".
