Infoworld’s antiSPF article

There is an article over at infoworld, , about a ciphertrust study of SPF.
Ciphertrust reports that only 5% of mail is using SPF and of those using it with correct syntax an even number of spammers and legit sites are using it.
Infoworld breathlessly reports this in a manner that would indicate that even before the standard is ratified it has been circumvented by the spammers. Those that continue reading down the page find this really isn’t true.
SPF is not intended to end the problem of spam. It is intended to end the problem of mail spoofing. (Sidenote: microsoft’s implementation SenderID apparently only checks the visible header, not the envelope header, so this apparently wouldn’t solve the problem of the forged envelope from resulting in employees getting virus notices from other companies for messages they didn’t even send.) Spammers registering their domain names with SPF doesn’t allow them to continue to spoof valid addresses.
The real problem with SPF is the lack of implementation by major players. Even commonly phished credit card companies and banks haven’t jumped on board. The article points out only 31 of the Fortune 1000 have SPF records.
