Well, I don’t know about the CCChiP problem, but I can say that since the shutdown of McColo on or about November 12, my spam has decreased…but only in my Google Gmail inbox.
On the other hand, it has DRASTICALLY INCREASED in terms of the spam floods on my SMTP and POP servers. To the point that it basically shut down the email servers at my business for much of the day today.
All the floods are coming from the Great Red Spot. All the inbound addresses point East.
