It is the evil web-mail I use, which use HTML by default, no fancy formatting.

I was just following some online examples of firewalls, for instance
the one on the arch wiki:
https://wiki.archlinux.org/index.php/Simple_stateful_firewall
which states:
This can be done with netfilter instead if statistics (and better logging) are 
desired:
# iptables -t raw -I PREROUTING -m rpfilter --invert -j DROP

Anyway, rpfilter can only be used in the raw table, I think.

By the way, filtering in iptables seems not exactly identical to rp_filter in 
sysctl.
The one in iptables blocks messages from 0.0.0.0 to 255.255.255.255. Sysctl 
doesn't.
