I tried using an e-mail address "@"@example.com in postfix. When I try to

with the error message

501 5.1.3 Bad recipient address syntax (state 13)

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
why are you try using such addresses?

it does not matter what some validators or even any RFC says
special chars should not be used because ANY relay-hop has
to accept used senders and RCPT or your email will not get
delivered finally

means: even if you can configure YOUR postfix you will
not be able to do it for the rest of the world

"0-9" and "a-z" are the safe chars


Well someone has to start implementing the standards correctly or there is no point in making them anyway.
