Agreed!  I'm not actually suggesting that we want to do DKIM signature
checking -- i'm just pointing out that if we're worried about header
removal damaging any sort of cryptographic signature, that's the most
likely scenario where that'll happen.  The other forms of cryptographic
signature (PGP/MIME and S/MIME) aren't likely to be affected by header
stripping.
