using the character @ in the local part

[Michael Blessenohl]

Hi,

I tried using an e-mail address "@"@example.com in postfix. When I try 
to deliver a mail to it, postfix rejects it 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.


Thanks for any hints.
