mail issues questions

[Dima (Dan) Yasny]

DKIM is a method of publishing a public key in a txt DNS record, with which
the subject line of every email sent, is signed. When yahoo MTA's receive an
email, they don't just check the PTR record, they also check the subject
line signature, with the public key available in the DNS records. If the
signatures match - email goes through, otherwise it's dropped.

And as for SPF: http://en.wikipedia.org/wiki/Sender_Policy_Framework
