More than a decade later, spam even penetrates the very best "insert whatever name here" technology. It is 2017 and apparently society does not understand why spam still exists. Of course, all of us know why there is still spam. //donning flame retardant suit (and tinfoil hat for good measure... ) For those that lurk to learn, or, for anyone with no pov on why there is still spam: ******************************** Spam exists because society does not agree on a single protocol to stop spam. (We do not all even agree on the definition of what spam is.) In society, some filter emails by DNS, some by IP number (worrying about dropping emails from co-located domains that have not updated their wordpress and are pumping out 1 legit email for every 1000 spam, etc etc - we should also discuss this sometime?) ******************************** The concern for "false positives" outrank that of sender reputation and is out of whack. (and we, society, do not want to change this) let us take a closer look at a practical (and factual) example of this imbalance: Fact: Both Google.com and Yahoo.com send out spam (unsolicited bulk email - where bulk is defined as more than one or two of the same email and unsolicited - as simply not requested or expected) Fact: We all receive many times more spam from yahoo.com as we do from google.com even though google.com transmits many times more ham than yahoo.com (Another simple truth: We all receive much more criminal activity from yahoo.com than from google.com) If you wish to dispute these simple and factual numbers you can look at the IP ranges in public data related to abuse, as the statistics report exactly the same facts that I am claiming (and experiencing)) Yet, we will be hard pressed to 'drop" incoming from yahoo.com simply based on sender score, we also do not use other RBL, that lists Google.com IP numbers, for drop. (as our users would have hissy fits if they did not get email from example@yahoo or example@gmail - in fact - they may simply move their email hosting to google... - because google/yahoo cannot be wrong, it has to be @example_of_small_isp... Our user(s) want to receive email from grandma, even though grandma has just dumped 10000 unsolicited emails asking for donations to send her old age club to the beach for "insert name of special and/or religious holiday here" Your thoughts?

Your thoughts?

Spam exists as ISP across the world, with some excemptions, don't do even the most basic procedures to detect and stop spam from their networks. Shame on them ( but it is cheap ) -- Peter H?kanson There's never money to do it right, but always money to do it again ... and again ... and again ... and again. ( Det ?r billigare att g?ra r?tt.

he believed that the "Penny Black" scheme would work... he was wrong, the bad guys have more resources to hand than the good guys and so a system based on proof-of-work could not be effective some of us explained this at the time ... http://www.cl.cam.ac.uk/~rnc1/proofwork2.pdf - -- richard Richard Clayton They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety.
