relayhost, as documented, sends mail that isn't for the machine
itself to the relayhost.
However you can override relayhost, as documented, with transport_maps.
So one example is:
/etc/postfix/main.cf:
transport_maps hash:/etc/postfix/transport
relayhost = [smtp.isp.nl]
/etc/postfix/transport
.localdomain smtp:
(instead of localdomain specify your local domain name).
