It is not common nor wise to have X-Spam-* header fields included in a DKIM signature. Neither amavisd nor dkim-milter/OpenDKIM or dkimproxy would do it, without special effort. I wouldn't expect striping of X-Spam-* header fields to be problematic in view of invalidating signatures. What can be detrimental to signatures is modifications to existing header fields like From or Subject by inserting 'tags' like **SPAM**. Whether this matters or not depends on what will happen next with such mail. Mark
