I am wondering if there is a way to stop spamd from processing a message if it was originated inside my network. I thought the "-i 192.168.0.0/24" flag to spamass-milter would take care of it but it appears from my /var/log/maillog that all messages are from "127.0.0.1" no matter where they are coming from.
Does anyone have any thoughts on how to only scan incoming messages for spam?
