That's not a Postfix rejection message. Show logs & postconf -n.
I defined an alias, so in theory it should work. The recipient
address is totally valid as far as I know and as far as online
validators tell.
It is valid. It is not sane, but indeed, with proper quoting as
shown, it should work.
Replaced my domain name by example.com, IP address by XXX.XXX.XXX.XXX
and hostname by hostname
