According to my logs, this would be an accurate statement. I get hit by a lot 
of brute forcers trying *@domain and just tons of stupid spam drones.. Nearly 
all coming from dialup win boxes (according to p0f they are win boxes). 
Luckily cbl.abuseat.org and the other various rbl's do a pretty good job of 
keeping them under control. I very rarely see someone rejected as being an 
open relay.

However, the second someone has an open relay up.. it's a spammer heaven.
