Also, check your SMTP restrictions
smtpd_recipient_restrictions = permit_mynetworks,
reject_unauth_destination
This was the problem, the permit_mynetworks was about fourth in the list
after reject_nonqualified_name, puttting permit_mynetworks first allowed the
traffic to flow through the server.

If they are local networks, make sure you have your DNS responding with
reverse lookups. You can make your DNS think it is authoritative for the
192.168.1... ip network.
Also, check your SMTP restrictions
smtpd_recipient_restrictions = permit_mynetworks,
reject_unauth_destination
smtpd_client_restrictions = check_client_access hash:/etc/postfix/access
Good Luck
