Came across the registrars list this morning, had me wondering out
loud what "DomanKeys" are and if its spf-based or spf-like. (I joined
this list after hearing a rumour that Yahoo was going to adapt spf
in the new year, until then I was only familiar with rmx)

It's not SPF by the looks of things.  It uses public keys in the
DNS and signatures in the mails.

Unlike SPF it potentially allows you to use your local SMTP
server and solves the .forward problem by allowing the reciever
to use the original source to verify the mail, ignoring the
forwarder.

Also unlike SPF it either requires changes to the mail client
or to the SMTP server (in the latter case you have to use your
home, not local SMTP server) in order to add the signatures.
And potentially in order to ignore the signatures at the receiver.
