Gmail Begins Signing Email with DomainKeys

Posted by timothy on from the early-adopter dept.

NW writes "According to a post at IETF's MAIL-SIG list, Google has begun to sign outgoing email from Gmail with Yahoo's DomainKeys signatures. This is the first large provider of email that is actually doing so (not even Yahoo has started that yet)."

  1. Domain Keys question by Anonymous Coward · · Score: 5, Interesting

    I have a web domain mainly to receive e-mail.
    When I send mail, I use my domain in the "from."
    However, my domain provider doesn't allow smtp, so my outgoing mail is through my ISP.
    If my ISP supports domain-keys, they will sign my outgoing mail, but it will NOT match my totally-legitimate "from."
    According to the domain-keys summary, this would flag my mail. In medical terms, this is called a false-positive.
    How does domain-keys prevent something like this from being a problem, other than by forcing users to adopt a completely different e-mail stragegy?
