Well what do you expect would happen when the first of these restrictions is
permit_mynetworks? From TFM:
permit_mynetworks
Permit the request when the client IP address matches any
network or network address listed in $mynetworks.
Note that this check is on the IP address that connects to the server, not what
it says in the HELO/EHLO handshake. Those checks come later in your config. But
they won't get tried when the connecting IP address has already matched
something in $mynetworks.
