SenderID and SPF works a lot better since not everyone controls their own

SenderID and SPF works a lot better since not everyone controls their own reverse DNS. Setting up a regular forward DNS is trivial; setting up reverse DNS isn't and that's why rDNS isn't a reliable metric. SenderID and SPF are also targeted to email applications but all three methods break forwarding if the forwarder is outside of your domain.

DomainKeys is a superior solution because the digitally signed messages can be relayed through any number of mail servers. DomainKeys also offer non-repudiation which makes it easier to tally reputation services.
