$relay_domains is for listing domains that you are willing to relay mail TO,
from anyone/anywhere.  e.g domains that you are backup MX or uucp host for.
etc.

$mynetworks is for listing IP addresses and networks that you are willing to
relay mail FROM, to anywhere.  e.g. your LAN.

that's because you've misunderstood how relay authorisation works.  relay
access is authorised by IP adress, not by domain name.

add "192.168.0.0/24" to $mynetworks in main.cf and run "postfix reload".

ps: see www.postfix.org for documentation and links to howto sites etc.
