UNIX and Linux Applications

Hello. Let's say as an example I have the below mynetworks list and the MYNETS policy bank set up to allow these networks to bypass spam filtering. But let's say I have a single IP within mynetworks that I don't want to bypass spam filtering. Let's call it 192.168.10.10. I've tried just inputting !192.168.10.10 but that didn't seem to work. So how do I do it? My next idea would be to create another network list with that one IP and a new policy bank that doesn't bypass spam filtering but I am not even sure how to create the policy banks. This server is in production so I need to know before I start messing about with the configuration.

Also, I have another problem. When the mail server sends its reports each night, they are getting filtered. They shouldn't be getting filtered because 127.0.0.1 is in the mynetworks list. The server's external IP is also in the mynetworks list so what the heck? Thanks!

Code:

@mynetworks = qw( 127.0.0.0/8 [::1] [FE80::]/10 [FEC0::]/10
                  10.0.0.0/8 172.16.0.0/12 192.168.10.0/24 );

Code:

$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
  bypass_spam_checks_maps => 1, # Allow $mynetworks to bypass spam checking.
  bypass_banned_checks_maps => 1, # Allow $mynetworks to send any file type.
  bypass_header_checks_maps => 1, # Allow $mynetworks to bypass header checks.
};
