Two Weeks Out, Spam Volumes Still Way Down
A full two weeks after a Web hosting firm identified by the computer security community as a major host of organizations engaged in spam activity was taken offline, the volume of spam sent globally each day has yet to bounce back.
The block graph over at e-mail security firm IronPort suggests that the company blocked around 35 billion spam messages on Monday. Prior to hosting provider McColo's shutdown, IronPort was flagging somewhere around 160 billion junk e-mails per day.
A quick glance at the volume flagged by Spamcop.net shows that they're still detecting well below half of the spam volumes they were just two weeks ago.
I'm not suggesting this is a permanent situation: I happen to agree with most experts who have said they expect spam volumes to at some point bounce back or even exceed previous levels. Still, it is nice to see this drop in junk e-mail largely persist for so long.
To the many readers who have written in to say "Bah humbug! I haven't seen any drop in $@!#* spam!" I would like to refer you to the excellent point made by Cloudmark's Adam O'Donnell, who in our follow-up story last week explained what he thinks is going on there:
Not everyone has seen fewer spam messages in their inboxes after McColo's shutdown. Adam O'Donnell, director of emerging technologies at Cloudmark, an e-mail security company in San Francisco, said those who did not see a drop in spam from the McColo shutdown likely subscribe to an Internet service provider that already does an effective job blocking 99 percent of junk e-mail.
"People who had really good systems in place probably didn't benefit from this, while those who had more marginal spam filter protection likely saw a significant drop off in spam," O'Donnell said.
