If there is something wrong you will see the error when you do: postmap hash:/etc/postfix/client_checks For failsafe, make changes to a copy of client_checks in another location and then postmap this, if no error then copy the amended client_checks file into /etc/postfix and postmap there. The changes will be implemented in active postfix pretty quickly after postmap, but to force immediately do: postfix reload
