In the scheme proposed by Art Pollard, a copy of the public key would be 
included with the signed message. Common format for public key certificates 
use base 64 encoded, outright ban of all base-64 email would be a problem 
for this. The point I was trying to make is that outright ban on ALL 
base-64 email is not a simple as it sounds. There are legit applications 
that use it and such banning approach would have to take them into account.
