Postfix ip block
Dynamically build your reject_client list based on ip blocks of well known assholes.
Add new ip block
Simply add the first three octets of the ip addresses that are giving you guff to the ip_blocks list in block.py
ip_blocks = [
'185.45.193.',
'109.206.177.',
'62.113.250.'
]Set the reject_client path
Based on your os, your reject_client file might be someplace special. For centos, the path is /etc/postfix/reject_client.
Just set your path as the first argument.
python block.py <path/to/reject_client>
All setup?
chmod a+x block.py
python block.py /etc/postfix/reject_client
