Link: http://antispam.yahoo.com/domainkeys So, what's everyone take on this? As with every anti-spam method, it needs to be widely accepted before it can be usefull. I guess it would be a good addittion to the rest of the anti-spam tools (like white/black lists, CRM, Bayes and so on), but it would require new modules for the most MTAs out there. I guess in the end it will just turn into another spamassassin score... Bojan
