To drop or not to drop, that is the question. If there's a server
out there sending spam e-mail, and I use iptables to block it, is it
best to simply drop the packet, or should I do a '--reject-with
icmp-host-unreachable' (or 'icmp-port-unreachable') or just a 'tcp-reset'?
Basically, if I just drop the packet, the server in question would
simply continue to send stuff, wouldn't it? As far as it knows, its
spam reached the destination, whereas if I send something back, it might
actually acknowledge and stop? Yes? No?
