Sorry, I'm trying to close languishing tickets.  Feel free to reopen especially
if there is any data to support opening the ticket, wonderful.  

But right now, I think there are a lot of strikes against SEM being implemented
and no reason to keep this open.

Of course, I also take primordial joy in closing tickets.  Sort of the same joy
I get in balancing my check book monthly. Don't take away my joy ;-)

> a)  Does SA properly handle the "refused" return code from DNS resolvers? 

No, because that refused code is non-standard. I guess if the RBLs want to help
us implement the code AND we implement it AND we wait until the old versions
are EOL, then we could implement RBLs.

> Should we care that other software does not, even if SA correctly handles it?

Yes, we should care because it can't be standardized easily.  It's a problem
that doesn't have a good fix because of the use of DNS as a distributed
network.

No, because many places just deal with RBLs as yes/no and don't care what net
block they belong to nor do they pay attention to bitwise answers.  

Some RBLs run combined and non-combined lists because of this.


And for the record, I agree with Warren on keeping it in masscheck for
virtually identical reasons.
