afaik, this is not possible with stock qmail (Turbo may know better), but it can be done with netqmail (a DJB-approved version that was put together by some of the high-profile users and developers on the qmail list), and it's trivial to do using qmail-ldap. For netqmail, which, most notably contains the QMAILQUEUE patch, you can implement the recipient checking in the alternative queueing program. I also, at some time in the past, did a patch to qmail that checked against a flat file of email addresses, one per line, and with qmail-ldap, which also contains that patch, you can configure a simple switch (set RCPTCHECK="1" in your tcpserver's access control file) that will cause qmail-ldap to reject all mail addresses it can't resolve using either LDAP only (this is what I use), or LDAP + system accounts.
