Interesting quote regarding SPF and those that advocate it:

"Except for the special case of bulk mail sender authentication by inbox
providers, no one with non-trivial operational responsibilities has
paid attention to SPF for several years.  At this late date, advocating
SPF for anything except whitelist authentication, ridicule, or an object
lesson in letting marketing and personality cult outweigh reality is
trolling or proof of willful ignorance."
