@joe
I can't say I totally agree with them, but I find the list useful. As I'm 
sure you know Joe, it's easier to drop at SMTP time with a DNSBL but to 
whitelist a ton of IP's (Cisco/Ironport have Gmails MX's running to 700+ 
results) upstream of that is not easy to implement. It ends up, 
typically, being done in the content scanner after the DNSBL checks have 
run.

@shmuel
As far as freemail providers and Spam go, Yahoo is always top of my chart 
for 101% spam and no ham. I rarely get it with Gmail or Hotmail now - but 
different folks see different streams.

I've got great faith in Michelle and SORBS generally, I've always found 
her helpful and knowledgeable and I'm sure she has justification to list 
it - I just think it's non nonsensical. They are way too big for their 
boots and communicating with Gmail, or their new adopted bastard child 
Postini, is a complete waste of anyone's time. If every blocklist nailed 
them, I suspect that problem could be addressed swiftly.
