excluding checks for @mynetowrks - amavis vs. postfix problem

[Tomas Macek]

I want to exclude some part of Postfix's mynetworks from Amavis spam checks, 
but really only some part, the rest should be checked as ussual. The "some 
part" is a subnet, in that I have all my servers sending emails, that should be 
excluded.
For example here I'm trying to say, that my servers (that I want to exclude) 
are in 192.168.0.0/29 subnet.

Our network is large - we use much wider range of public IP addresses, but
I will use a simplified this example only.

I'm using Postfix 2.8.4 with
 	mynetworks = 192.168.0.0/24 127.0.0.1

and want to setup amavisd.conf of my Amavis 2.6.4 to contain this:
 	# I think this will add only first 8 addresses to @mynetworks.
 	@mynetworks = qw( 127.0.0.0/8 10.0.0.0/8 192.168.0.0/29);

 	$policy_bank{'MYNETS'} = {
   		originating => 1,
   		os_fingerprint_method => undef,
   		bypass_spam_checks_maps   => [0],
   		bypass_banned_checks_maps => [0],
 	};

The doc of Amavis says, that mynetworks in main.cf and @mynetworks in 
amavisd.conf should be the same and @mynetworks should contain all the IP 
addresses of local network.

What bad will could happen if this will differ? Hope this will not lead to some 
complicated answer...
