[BlueOnyx:19856] iptables

hello

I'm still fighting with iptables against this mail-flooding to a specific user. I don't understand why mails from a specific IP like 123.45.67.89 still slip thru although they should be blocked if included within the subnet 123.45.67.0/24 ... I entered

# iptables -A INPUT -s 123.45.67.0/24 -j DROP -v

Reading the table with the following returns:

# iptables -L -n -v | grep 123.45.67.0/24
     0     0 DROP       all  --  *      * 69.168.97.0/24       0.0.0.0/0

What am I missing? Does iptables need a special configuration to be able to block subnets?

Thank you and best regards
