I looked at the code in Mail::DKIM which is what spamassassin and probably every other perl DKIM application uses. It checks the version number, and for some reason accepts "0.5" as well as "1", but nothing else. The most widely used python module is Scott's dkimpy, which checks that the version is "1".
