You can use an access map in the reinjection listener:

# master.cf
127.0.0.1:10026  inet  n       -       n       -       -       smtpd
...
  -o
smtpd_sender_restrictions=check_recipient_access,hash:/etc/postfix/spamtrap


OR you can add rules to your filter to blacklist mail addressed to
the spamtrap.

With DISCARD you must receive the whole message anyway, so don't go
overboard trying to optimize "soon as possible".
