If in doubt, read the documentation.
mynetworks (default: see postconf -d output)
The list of "trusted" remote SMTP clients that have more privileges
than "strangers". [more text omitted]
mynetworks controls the result of using "permit_mynetworks".
I suggest therefore that you examine the output from
$ postconf | grep mynetworks
(and with Postfix >= 2.9: $ postconf -M | grep mynetworks).
