yea... close all PoP's and "I can go and close my business ;)"

I don't know how it is in other countries  but here most of the customers 
are POP users. Direct lines ? Geee.. Only bigger companies can afford it. 

So when u get a spam, its from dial-line. most often.try to find who was 
it ?

there is an ISP called Polbox here in Poland. they've got about 50 000 
accounts ( people says that ). all these accounts are for free. 
people can get their www for free too... 
U can imagine what kind of people are on this server ( free.polbox.pl ).

or there is another solution:  
if all administrators will be consequent ( is it right word ? ), and not 
to give accounts to people who are on "Great Index of Spammers - year 
XXXX". :))) 

but this happens only in heaven :(
