on the DoS going on against our mail system …

Yes, someone with lots of machines in a .ru domain, is trying to send us lots of spam. Trying a DoS, but I don’t think its working all that well.
But what is troubling to me is that several of the machines listed give .army.mil addresses. Which, if they aren’t forged, says something profoundly bad about security on our armed forces machines.
Sure, they could be little spambots. Imagine if they were more than little spambots.
