In the future, you're likely to still be stuck doing this for other 'fun' 
reasons.  The one I ran into recently was that 8 bit -> 7 bit conversions will 
break DKIM signatures, so it's only safe (from a reliability perspective) to 
sign 8 bit mail if you know the entire path is 8 bit clean.  Since there's 
really no way to know that, now I flatten everything to 7 bit and then sign it.
