First ipv6 spam, and it's a good thing :)

Just started testing the new version of Cisco Ironport 7.61 which is their
first release that supports ipv6. We have it up and running and the AAAA
record setup for one of our MX servers. Started receiving mail today via
ipv6 with no issues so far. No surprise, got our first spam via ipv6 a few
minutes after cutover J.


It will be interesting to see how Senderbase and other IP reputation systems
deal with the larger address range of IPv6.
