They said they were emptying the zone files, not actually "listing the 
world" - so this shouldn't cause false any positives - but might cause 
some false negatives, especially for anyone who was overly relying on 
SORBS in their spam filtering? But yet - after some years - lists like 
this - once they've been dead for many many years - do sometimes "list 
the world" as a final push to get others to stop using them - if that 
even ever happens with SORBS? And if it ever did, I doubt that would 
happen anytime soon.

But definately make sure that your spam filter is ONLY ever acting on 
specific and valid SORBS return codes - and NOT treating ANY query being 
resolved that isn't NXDOMAIN - as a listing. Anyone misusing SORBS in 
that way - might one day have a very bad day. But that's a general truth 
for all DSNBLs - make sure your rules/setup for its usage only treat it 
as a valid listing when specific return codes are returned, that match 
that DNSBL's instructions, and thus NOT taking action just because some 
IP address was resolved by the query.

(I think any built-in/default SpamAssassin rules for SORBS - already 
does all of this correctly.)
