Certainly, the DKIM plugin already comes with a package, just needs to be enabled: loadplugin Mail::SpamAssassin::Plugin::DKIM It can be used for reliable whitelisting, and for inclusion in rules to catch phishing on popular domains (e.g. paypal, ebay, amazon), and to penalize to some degree mail claiming to be from domains such as yahoo, yahoogroups, and gmail.com but is not really coming from there.
