I thing SPAM is more a political problem than a technical one ! A lot of smart technical solutions exist for a long time now but SPAM remains a problem. If all the main mail service providers like Google and Hotmail would choose a technical solution against SPAM and rejected mail from servers not following these rules, I thing SPAM would be reduced to the minimum. These rules must also require the commitment of all mail actor, from the individual to the big companies and ISP. My favorite solution combine RBL and SPF pointers. Not RBL of IP addresses as usual but thanks to SPF we could black list domain names. If rejecting mail from SPF unaware domain was the rule, any SPAM could be easily attributed to a domain name and its company owner. Repeated SPAM flood would damage the corporate image of the company and incapable IT managers would be replaced by capable ones. RBL and SPF are now common, reliable and easy to use. Lot of of mail actor are already using them. Maybe we could start at our humble level to warn every senders about their SPF unaware domain name. Open source should provide such software, and RBL providers handle domain names instead of IP addresses.
