Hi,

This is what I know,
----------------------------
mynetworks = 127.0.0.0/8 !192.168.1.1 192.168.1.0/24

In amavisd.conf @mynetworks determines which clients will use the
'MYNETS' policy bank:

@mynetworks = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10
!192.168.1.1 192.168.1.0/24 );

And you would configure the 'MYNETS' policy bank as desired:

$policy_bank{'MYNETS'} = { # clients in @mynetworks
bypass_spam_checks_maps => [1], # don't spam-check internal mail
};
----------------------------
This should work, but the mail coming from local (mynetworks) is now not
being scanned when going to the outside world. This we DO want. We are
hosting multiple domains, so we must check on IP number, not domain name.
Your solution will make everyone from yourdomain.com a spam_lover ? Or
am I wrong ?

Greetings... Richard
