January 2015 ESP Spam: Some Notes….
I see that Atro Tossavainen graphed the spam that we saw in January. Atro and I manage a substantial spamtrap collection together, so I have seen what he posted about. Nothing there surprised me except the hugely disproportionate amount of spam Topica sends to our spamtraps. I’ve blogged twice about Topica, and in the last blog recommended blocking their /22 because of the amounts of spam and probability that little or no non-spam email is sent from them any more. However, I did not realize that we were seeing twice as much spam from Topica as from ExactTarget, which sends several orders of magnitude more email than they do.
