OK, but: Q: Are there any default rules as supplied by sa-update that would prevent SPF rules from firing? Q: Any other ideas on how to learn what rules are actually being used? Q: Any suggestions as to why SPF rules would not fire on a Gmail message where Gmail uses SPF, my SPF plugin and rule initiation seem to be in place, and a Return-Path header with the envelope from address exists?
