If you mean "How can I make my server reject mails with an empty (null)
envelope sender with qmail?", the answer is "Don't". Stock qmail won't even
let you try.
The reason for this is that bounce messages and other automated mail are
required to be sent with that envelope sender, and SMTP servers are required
(by the RFCs) to accept them. To do otherwise is to reduce the reliability of
the mail system -- you'll never find out if some of your mail was
undeliverable.
