Sorry, I was referring to messages received at my mail system that originate on Yahoo!'s mail system; more specifically, messages that are signed by a yahoo.com key and coming from a yahoo.com mail host (according to DKIM and SPF). Anyways... > "Yahoo doesn't consider a properly DKIM or Domainkeys email something that should not just end up in the spam folder" Nor should they. There's plenty of actual spam that passes SPF and DKIM checks -- which brings us back to my original point (the amount of spam that I receive from Yahoo!). A message should not be treated as non-spam just because it passes those checks -- they are merely one factor to consider.
