Here is some blueprint how you could try it:

    ... 
    warn
    add_header    = X-SECRET-Importance: 4711



And later in the transport (I'm using the amavis transport here, because
all incoming messages have to pass it):


    amavis:
    driver = ...
    headers_remove = Importance
    headers_add = Importance: $h_x-secret-importance



(I'm not sure, probably you can even remove the x-secret-importance
header in the transport - it's how I interpret the 43.17 section).


But again, I'm not sure, what we do with spamassassin is only similar, not the same!
