I keep a pretty close eye on my email volumes as I own a little anti spam company – you point your MX to me and I’ll deliver a clean set of email to your server, nothing too complex.
A while ago while looking at my overall flow of email I noted this drop:
I thought it might be an anomaly or just a short interruption but it’s kept at this limit for a few weeks now. The only thing I can imagine is that some big botnet got shut down or very prolific spammer packed up shop as my average rate of connections have halved as in the graph.
There was a well publicized story in the news recently about Google also seeing a drop in spam their’s doesn’t seem to suggest a sudden drop but my stats and the news from them certainly makes me feel better.
