[Users] dev/null

[Iqbal]

Hi

Anyone know howto /dev/null inbound requests, from users. Reason for 
this is that I have a few random setups, which I no longer support, and 
the user has xlite and is just sending through REGISTER requests, I'd 
much rather they just get dumped, prefer to do it within ser, rather 
than some iptables/fw block.

I guess I could have some blacklist table, and if From= blacklist then 
break...suggestions.
