Here's the link for a new Botnet only mailing list. Just got PR yesterday and already there's some interesting stuff flowing on it.

You may want to drop this message out there.

I've been getting a lot of what appear to be spam bounces the last week or so. I'd usually ignore them, but this isn't 
typical for me, or anything I've seen before.

I perhaps 150 bounces a day. In the past, I'll get a huge rash of these all at one time, and for a day or two. Then it'll 
cease. Further, they've all come from the same sending machine in the past.

Here's a quick sampling of the sending headers info.

Is this typical, and should I just put up with it? I assume it has to be a bot-net since I'm getting these from a whole 
host of machines, and it would be unlikely to pick my addy by random on a whole host of spammers at the same time.

What's interesting though, is I'd expect to practically drown under the load - thousands or tens of thousands of bounces if 
a botnet was using a single from: addy. Are they picking a huge pool and round-robin'ing them?

Curious. TIA.
Greg
