First IPv6 Spam Message Caught in the Wild

By Ken Simpson | 4 minute read

Greg Troxel reported on the SpamAssassin users mailing list today that he had received the first spam message sent via IPv6 (the successor to IPv4, the Internet Protocol addressing system).

The anti spam community is very concerned about IPv6 because its enormous address space will enable spammers to have access to a virtually unlimited number of IP addresses, rendering traditional “black lists” obsolete. When spammers start sending through IPv6 in earnest, receivers will have to rely on reputation-based whitelisting, treating new IPv6 addresses with a great deal of suspicion until they establish themselves to be trustworthy.
Could this be the end of Spamhaus and other venerable blacklists? Not so fast. It will take decades for IPv4 to be phased out in favour of the new standard. And until that happens, blocking will remain an indispensable technique for stopping spam.

The raw message looks like this (Link):
