Aah, so the personal subdomains are catch-all accounts? So one doesn't have to talk to the Relay services at all and can just give out whatevertheycanthinkof@yo

Aah, so the personal subdomains are catch-all accounts? So one doesn't have to talk to the Relay services at all and can just give out whatevertheycanthinkof@yourname.mozmail.com and it would get forwarded? If so - thank you, yes, now I see the point. My bad and please consider telling marketing team to highlight this hotel use case more prominently, because without it just comparing @mozmail.com vs @foo.mozmail.com is not really compelling and could be even confusing.
