+#"To pass DMARC, a message must pass SPF authentication and SPF alignment and/or DKIM authentication and DKIM alignment. A message will fail DMARC if the message fails both (1) SPF or SPF alignment and (2) DKIM or DKIM alignment."
+#
+# We expect edge cases with DKIM where a parent (gateway) domain signing for a subdomain author (e.g., parent.gov signing for sub.parent.gov). This is a common and a sane implementation of DKIM, but is not supported in the current SA DKIM/DMARC implementation -- it results in DKIM_VALID but not DKIM_VALID_AU. The SPF || DKIM logic below will allow this scenario.
+#
+# Note: Certain glues like MailScanner will modify an email before testing. That will cause many DKIM failures. If you have a known broken system for DKIM like this, you should likely disable the plugin.
