One of good reasons to NOT enable IPv6 may be the thing I heard when I was dealing with my problem of being classified by Google as spam. Someone told me (of course it's not confirmed, as there are virtually no confirmed informations about how Google's anti-spam filter behaves) that Google is more likely to classify email from small senders as spam if they are sent via IPv6, and less likely if they are sent via IPv4. -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub."
