SMTP Conversation:
-----------------------------
If you see it, when I use user@domain, the check is done by qmail-smtpd
and reject in smtp conversation if its necesary. But if you only insert a
user name, qmail-smtp always accept the message and then, qmail-send show
an error at log level without inform to sender (delivery 1: failure:
Sorry,_no_mailbox_here_by_that_name._(#5.1.1)/)o .

I want that always qmail-smtp block the send of message if user doesn't
exist. Is it possible?
