I haven’t worked with Dave Crocker in a long time, and it is nice to catch up with what he is doing, particularly the whole Domain Keys effort to try to get email sender authentication standards. A working group of 20 of the largest emailers, including Yahoo, Google, AOL, and Sendmail, gathered together this past week in Dallas to try to iron out interoperability issues. While this is “just small brick in a very big wall” according to Crocker, it is a positive step towards fighting spam and reclaiming email as a useful tool from the spammers and scammers.
