Subject: [OT] (maybe [Admin]) Spam and Mailing Lists

I just read an article in USNews&World Report about the ISPs' fight to
destroy email spammers. The key innovation they developed is one that
wouldn't affect person-to-person emails but would eliminate spammers.
How? Simple: before delivering an email, have the computer of the
person sending it perform a complex mathematical problem (taking,
perhaps, 5 to 6 seconds of processing power to solve) and THEN
delivering the email.
It mentioned in the article that if you are sending out an email to
one or two people it didn't affect you, but if you are sending
something out to one thousand or two thousand you will notice the
So? Why am I sending this out? Because this is a mailing list, and so
the central server ( would have to spend 5 or 6 seconds
processing the math problem for each message to each person and in one
day, that's a lot of computations it's doing. I don't know if the same
server also hosts the Dumpshock pages, but if so, that traffic would
be affected.
I also don't know if this is in use yet or if the bugs are still being
ironed out, but I figured Admin and Gridsec needed to know about this.
Better safe than sorry. :^)

These messages were posted a long time ago on a mailing list far, far away. The copyright to their contents probably lies with the original authors of the individual messages, but since they were published in an electronic forum that anyone could subscribe to, and the logs were available to subscribers and most likely non-subscribers as well, it's felt that re-publishing them here is a kind of public service.
