You're wrong here. While ipv6 provides delivery path tracking capabilities
(which may or may not be supported by in-between routers) for ip
packets, this is different communication layer and only helps in tracking
where ip came from and what routers it traversed, this has nothing to do
with SMTP where each mail in itself can be thought of as packet
traversing serious of nodes and for email path tracking is basicly the
received headers. I will not go into more details here, but if you want to
understand more, please read good book on networking or see:

IPv4 and IPv4 are network layer, while SMTP is application layer and one
does not help the other that much at least in our case.

I am not sure what the chances of IPv6 are of ever making it into the real
net, however for completeness reasons we should include its as part of a
solution that will make the job of tracing spammers much easier. Also it
will make blacklisting / watching address blocks possible because of the
hierarchical nature of IPv6 address allocation. There might be something in
the proposed 1to1 mapping between geographical areas and address blocks
allocation.
Spammers will not be able to hide anymore, or make the job of hiding
hardware intensive, therefore more costly, thus changing the business model,
hopefully crossing the line into making it non profitable.
