I have been trying to block email form a block of ip addresses.
I'm using e-Smith 5.6
I used the command
iptables -A INPUT -s xxx.xxx.xxx.xxx/24 -j DROP
when I run iptables -L INPUT
it shows
DROP all -- xxx.xxx.xxx.xxx/24 anywhere
Yet email from blocked ips keeps getting through.
Can anyone tell me what I'm doing wrong?
Thanks for any help.
