The discussion in this thread has also included bot and crimeware netblocks.. As for the 'good enough spam filter' versus giving spammers and botmasters an unlimited supply of IP space, it starts to remind me of those high school maths problems where a burette empties out a tank while a firehose fills it up People with good enough spam filters to run mail for millions of users each will tell you much the same thing --srs (htc one x) <div class="gmail_quote">On 28-Jun-2013 3:09 PM, "Jørgen Hovland" <<a href="mailto:jorgen@hovland.cx">jorgen@hovland.cx</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Den 6/28/13 10:50 AM, skrev Frank Gadegast: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Sascha Luck wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> On Fri, Jun 28, 2013 at 09:47:35AM +0200, Frank Gadegast wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> What about a RIR regulation to ensure that address space is only used for purposes not harming anybody ?

I would rather see a regulation that would deny address space allocation to LIRs not having a good spamfilter. <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> For a start I would like to force resource holders to actually read the mail arriving under their abuse address.

Accepting your abuse mail is not a right, but a service. This may be unfortunate, but it should be up to each LIR to decide if and through what media they accept complaints. Creating a standard and encourage all LIRs to use it would however be great. <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> </blockquote> </blockquote></div>
