Caller ID, Domain Keys, SPF

Larry Seltzer (eWeek) compares, contrasts, predicts
Who Will Win the SMTP Authentication Wars?:

This isn’t like three brands of bleach, where you’ve got the same chemicals in all three bottles. In fact, the more you look at these standards, the more different they look. I had been fearful that having three major standards competing would be discouraging to the market, since explaining even one of them isn’t easy. And consider that the three major mail providers in the United States—AOL, Yahoo! and Microsoft—are implementing the three different standards. I think, however, that the three, or at least two of them, could complement each other. The ideal solution may be all three, or some later standard that combines the features of two or three.

  1. Since I am using NoSPAMProxy to filter mails based on CallerID and SPF I have much less Worms coming in ;-)
    Finally a great System. Just a pitty that Microsoft again tries to compete with others instead of simply supporting them :-(
