There was a thread on either NANOG or v6ops-ietf (I can't remember) a 
couple of weeks back where numerous people stated they were receiving 
spam via IPv6.

If memory serves me correctly, one person claimed up to 50% of all email 
received via IPv6 was SPAM.

If I can find the thread, I'll post a link.

On my box I've been working on, I've got SpamAssassin operating at this 
point.

Once I move a couple of live domains on it, I'll be able to compare 
relative amounts of spam coming via each protocol.

Indeed.
