Good Day,
I have attempted to blacklist a large block of ips in MailWatch (take a hammer to kill a fly you know) such as: 1.0.0.0/8
yet moments later, a new SPAM comes in from an ip within that netblock - any tips?

Try just entering the network portion of the IP you want to block, like 123.123.123 (for 123.123.123.0/24)
