On my relay, I tried these settings:
local_transport = error: local mail delivery is disabled
mail_version = 3.5.8
relay_transport = hash:/etc/postfix/transport
.our.local.domain relay:[MDA server IP]
smtpd_recipient_restrictions = permit_mynetworks
relayhost = [ upstream relay ]
And when I send mail, I get "Recipient address rejected: local mail delivery is
disabled"
What am I missing, please ?

.our.local.domain relay:[ MDA server ]
The '*' is not needed because you can use relayhost or default_transport.
