Well, that is as good a suggestion as the method of the kill file.  It          
works only if you know the "user-x". As you have seen, if "user-x" goes         
for a face lift, and becomes "user-y", then he bypasses kill files or           
filters in the news servers.

There are not any other users at his site. In fact, there is no site at         
all :-).  He achieves this by posting through the anonymous posting             
facility of the "Ucbvax.Berkeley.Edu". It is too easy for him (or               
anybody else for that matter) to forge a user-id and a domain park. In          
fact it is a common knowlege among his cycle. One of his friends forged         
my id and domain recently, by posting through "ucbvax".  So he is capable       
not only avoiding mail bombing, but redirecting it as well.

The common thread is "Ucbvax.Berkeley.Edu".  This is where his "tail"           
is.  A lot of netters complained to the "postmaster@ucbvax.berkeley.edu"        
about forging, crossposting, etc.  The result was to move most of the           
sendmail aliases pointing to *individual* Usenet newsgroups. This is            
really strange, as they have kept the alias "post-usenet" (which I              
am using now), which posts and crossposts to any newsgroup via e-mail.          
I think the system administrators from "Ucbvax" are loosing the trees           
for the forest, or they do not want to understand, despite the volume           
of complaints they receive every day.  They simply harbor forgers at            
their site, and they know it, as they have helped me to find one, by            
supplying me with their sendmail logs.  My suggestion is that the               
anonymous posting facility at "ucbvax" ought to be terminated first,            
before applying selevtive filters in NNTP servers.
