So you have two ways:
First the bad way: Kill your rcpthosts which will cause your server to be an
open relay. A variation of this is checking the sender address (see
qmail.org for this patch) which is easy to fake, so your an open relay
again.
Second the good way: Apply one of the packages on qmail.org which allow
smtp-connections after an authentication over pop3. That's the way most mass
providers like gmx go. The pop3-connection saves the ip and you're allowed
to send mails for a certain time.
Third the other good way: Patch your qmail-smtpd to allow authentication
over esmtp. There's a package on qmail.org you'll have to use in combination
with a checkpassword program. If you use this, you need to use a MUA which
supports this smtp-authentication (like outlook, netscape).
Just have a look on www.qmail.org
