Udo,
You have just illustrated why blocking IP Addresses to prevent spam doesn't 
work.
At the moment I'm using my Blackjack PDA to reply.  Using mt wireless providers 
WAP SMTP server to send mail to the list aliased as my dialup address which is 
subscribed.  No return packet needed.  Further, trojan spam mailer servers are 
capable of answering IP requests.  I think this will be my last post about 
this, you are not looking at the big picture, only your web forum.  Ask 
yourself 1 question...Why are spammers targeting my forum?  Then make the forum 
subscriber only list and the spam  will decrease.
CU L8R!

Are you saying that the routers ignore IP addresses completely? Well,
that would be a wonderful thing, and most certainly the solution to the
problem with scarce addresses in an IPV4 network! ;-)

So tell me, how do the routers react if a packet is sent back to the
forged address? Do they really know where to send it even though the
address says that it belongs to the Asian region? ;-D

Mind that we are not talking about gateways to an isolated net here,
which are also commonly referred to as "routers", and which regularly do
NAT, but about servers whose sole purpose is to route the packets to
their destination in as few "hops" as possible. Would they really send
the packet to the router that the forged address came from even though
it does not match the corresponding sub net mask? About the only purpose
of the sub net mask is to make the routing of packets to the right sub
net easier, and you just say the Internet routers ignore it? I can't
believe this.

Regards,

Udo
