[dns-operations] [from nanog] in.dnsbl.org must not be used for mail filtering

[David Ulevitch]

Mark didn't mention it but there is some discussion about making it  
non-public (I support this).  It isn't to close out data from the  
public -- it's because whenever we find out about someone "public"  
using it they are using it in a terribly stupid way and have no  
understanding of what the in.dnsbl.org zone is for.

Is *anyone* out there using it for something?  Please let me know if  
you are using the zone and what for. (Rick, I remember you mentioned  
wanting a copy, ever get it?).

If you're a contributor to the dnsbl or the email list no need to  
tell me, I already know.

Speaking of which, maybe a brief explanation to the dns-op meeting on  
Friday about how the most of the dynamic or free dns providers  
collaborate and share data would be in order.  We've got a lot of  
automated and non-automated ways of sharing data (Most of which are a  
credit to Mark Jeftovic, who has recently handed a lot of  
responsibilities to Tim Wilde and I as he just became a father).

Thanks,
David
