I have two networks - one with public ip addresses and one with private (192.168.0.x).
I have some servers in both networks, and some in private only. Logwatch and other similar programs work fine for servers with public addresses, but I do not any mail from those with private addresses only (they can access the the iRedMail server over NAT, or localy (192.168.0.x), local dns points mail to local address.
