Either verify the user's existence in Postfix (I don't really know how,
more of a postfix-users list question), or use something else than
passdb pam + userdb static. There's just no way to ask from PAM if a
user exists or not, and userdb static gives the same values for everyone
so it can't verify users' existence either.
