actually this ACL simply adds headers, to bypass SA should be smth like

deny   condition = ......
       spam = nobody/defer_ok
       ! local_parts = postmaster:abuse
       ...

in my example simply take out the ! local_parts line ...

As a side note, on our clients mailservers, for postmaster/abuse we
just skip RBL/blacklists checks but
not SA checks, else we'll get 10x times the spam we have normally...
