Before I get into email business(I run my own email forwarding service[0]), I don't understand why provider block those domains.
Then I immediately got it. The amount of spam emails from .xyz .click .faith .top is huge. And with every email comes from them, we have to run spam scanner, which isn't cheap. So we have to score those TLDs more sensitive.
