I block comcast DUL space. I whitelist their SMTP servers.  Cuts down alot 
of spam that way.  Did you know that Comcast added Kelly Joe Ellis and 
Brian Haberstroh to its stable of spammers just this month?  One more 
spammer and they'll be at the 100 spammer mark. Looks to me like someone 
blocking them knows what they're doing.

If you want to stop spam, then you have to block the ISPs who host 
spammers.  There really isn't any other option

As long as the Brazil ISPs universally think they have the right to shove 
their spam down our throats, I'll block brazil.  I just did a fast scan 
down the Brazil list, and couldn't find any ISPs with no long term spammers 
hosted.  linx.net is right that ISPs who host spammers should be de-peered 
until the spammers are cancelled.  Brazil hosts almost as many spammers as 
Comcast does.

What would your Brazilian friends have us do? Ignore the fact that their 
ISPs are harboring criminals?

Found 47 SBL listings for IPs under the responsibility of brasiltelecom.net.br
Found 41 SBL listings for IPs under the responsibility of embratel.net.br

And the ones with 2 or 3 spammers have been hosting the same spammers since 
2003. My server, my rules.  When they terminate their spammers, they can 
connect to my machine.  Non spamming Brazilians are free to smart host 
outside the country.
