I believe you can set up postfix to use reject_unverified_recipient in
the smtpd_recipient_restrictions portion of your main.cf, and set up a
list of valid recipients in the address_verify_map configuration
parameter.

I use address_verify_map on my
amavis+greylisting+spamassassin+virtualdomain postfix setup where I'm
also doing spam filtering for a friend who insists on running an
unprotected Exchange server for his personal email.  It works well for
what I'm using it for.
