Yahoo! Mail Issue

Well yahoo's mx tend to do that a lot. i used to have a lot of  bounced
emails to yahoo until i implemented dkim, domainkeys and spf then all my
yahoo problems disappeared ,

I just want to know if you have implemented any of
these technologies dkim,domainkeys and spf, other wise you would have all
those problems
