I've had that same argument with an online journalist on that subject. I really do think that whitelist for personal email accounts would do a world of good.
It is a sad fact that spam works if only one in a million take the bait. That means that 999,999 people get spam because one idiot actually ordered that bottle of Viagra from a dodgy website.
In my opinion, if whitelist email is implemented automatically, then the spammers will see a dramatic drop in the amount of hits they actually make, while normal people will see a dramatic drop in the amount of spam they recieve.
On top of that, add a mail tax for every mail above a hundred per day, and spammers will quickly realize that their business is simply not sustainable any more.
And when spammers abandon the premises, companies will be left with less of a burden on their mail servers. Whitelist filters will gradually be obsoleted, but ready to be put back in place if ever a new spam surge happens. Everybody wins, as far as I can see.
The jounalist didn't agree on the grounds that, if whitelists existed, I couldn't have contacted her to discuss the subject. She obviously overlooked the fact that, as a professional, her professional account would not have a whitelist, so I would be able to contact her.
Pascal.
I've got nothing to hide, and I'd very much like to keep that away from prying eyes.
