That is not right.  People who operate relays may be less culpable than

The term of art is 'contributory negligence'





That is the term, but only a very few years ago open relays were

the norm, even the polite thing to do. 


There are many things that once were okay, or at worst ignored, and are 
now as much as outright illegal.



You used to be able to get a full Usenet feed at 300 baud.



Society moves.  The Internet moves faster than most things.




Anyway, the point is the open relay operators are not doing things
deliberately.  They don't want to relay spam.  They are spammer's
victims.  If possible, we should try to help them.




Agreed.



I firmly believe that blacklisting open relays being used to spam is one 
of the simplest and most effective ways to help them notice they have a 
problem.  Trying to contact relay owners is usually a waste of time due 
to poor WHOIS practises. Demonstrating that running an open relay has 
real consequences is what gets them to pay attention and fix their problems.



Blacklisting relays generates the occasional false positive here - but 
our infrastructure takes special steps to ensure that any rejection is 
seen, with instructions on what to do to rectify the situation.



In that sense, our system has no false positives - there's always a 
means to get the email through. Just may take you two tries.




Forcing them
all to close is something to be done only if we have exhausted all
ways to solve the problem.




That's silly.  The problem _is_ that they're open and usually being used 
to spam, and the quickest and most appropriate way to solve the problem 
(in 99.99% of the cases) is to close them.  Ignoring a spam hydrant does 
nobody any good.
