Although I phrased my question in terms of a kill file hit, the original 
thought (as I've just mentioned in another follow-up) was to do with how to 
handle mail that had a malformed RFC 822 header. This may seem a minor 
point, but as my server may be acting as a mail relay or passing mail onto 
third party code modules for handling there may be benefits in guarantying 
that headers in forwarded/delegated messages are valid. The mail kill 
possibilities only struck me later.
