yeah (there is no local users at this box :) )

I thought on this, but there aren't. see

$ grep bussola /etc/postfix/virtual
userbussola.jor.br owneremail.com
webmasterbussola.jor.br userbussola.com.br
abusebussola.jor.br abuse
postmasterbussola.jor.br postmaster
$

(I don't use bussola.jor.br whatever as stated on virtual(5) because
all domains have a transport domain.com maildrop: and appear as
userdomain.com on maildrop's userdb table -- the fallback does
the delivery the right way (TM))

if you try to actually send a mail to the unknown user, it returns
back saying that he is invalid, but the vrfy acknowledge of an unknown
user as valid is anoying me.

perhaps the vrfy stuff is being caught by some default postfix
privacy behaviour? any other clues?

Thanks for answering
