That evaluates to PERMIT.

That has RBL checks without check_client_access exclusion, therefore
the above RBLs can reject mail from the client that you want to
exclude from RBL checks.

That has no RBL checks.

And that has some RBL checks witihout check_client_access exclusion,
therefore the above RBLs can reject mail from the client that you
want to exclude from RBL checks.

Now, what was the complete Postfix reject response. It would
name the RBL and provide a clue where the client exclusion is
missing.
