Domainkeys uses digital signatures and SPF seems to be like microsofts 
callerid system. They all have the same problems: 

- I have a few email addresses. When I send email from home that is work 
related, I set my From: address to my work email. When I send 
sourceforge-related stuff, I use my sourceforge address. This mail would be 
bounced using any of these systems because the mail gets sent from my home 

- Implementation is optional. If I'm sending SPAM, I only need to find one 
domain in the world that doesn't have this system implemented, and send all 
my spam using From addresses in that domain. Remember that this domain only 
has to exist, it doesn't need to even have an email system.

- And they assume that DNS is secure and un-spoofable.
