I don't fully understand what the role of the inbound service is on "setting headers". I believe SPF/DKIM/DMARC are mostly (not fully) DNS verifications. Shouldn't these be setup by the domain owner (sender/outbound)? Is the problem that they don't do the verifications for SPF/DKIM/DMARC for inbound emails?
