Invalid recipients are not rejected by qmail at all; qmail accepts 
messages for any user and later bounces them if the recipient doesn't 
exist.  This makes qmail a prolific source of backscatter spam.

Even if qmail did reject invalid recipients, however, spamdyke wouldn't 
be able to use its return code.  This is because the graylisting 
rejection must take place before the recipient address is sent to 
qmail.  Once a recipient address has been added to a message, there is 
no way to remove it without closing and restarting the connection.

I've been working on adding recipient validation to spamdyke and it's 
basically done.  I'm currently fixing some other bugs and testing the 
new features.
