I have just done more testing, and cannot get this working.  I even 
copied exactly what I have for @mynetworks from my old system, and made 
the change right were the default in amavis.conf is instead of appending 
it to the end.  No change.

@mynetworks = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10
                   10.0.0.0/8 172.16.0.0/12 192.168.0.0/16 );

And this server is at: 192.168.192.14/24

The old system is running: amavisd-new-2.6.4-2.el6
and the new one: amavisd-new-2.10.1-5.el7

Also BOTH .confs define policy_bank as:

$policy_bank{'MYNETS'} = {   # mail originating from @mynetworks
   originating => 1,  # is true in MYNETS by default, but let's make it 
explicit
   os_fingerprint_method => undef,  # don't query p0f for internal clients
};

And no where is MYNETS defined on either system's .conf

?  Puzzled

WAIT!!!

The old server is at:  50.253.254.3/28

and that is not EVEN in @mynetworks!

And the other servers are on 50.253.254.0/28 and they do not get the 
Open Relay message!

Something else is at work here...
