Strictly speaking, there must be a dunno/permit for each individual restriction in each stage. Order matters, of course; a permit action terminates the processing of further restrictions in that stage. But in this regard a header_checks rule is like a restriction stage unto itself. -- Offlist mail to this address is discarded unless "/dev/rob0" or "not-spam" is in Subject: header
