David,

InputForm (and Copy As Text) have no effect at all on Greek symbols,  
at least on Mac OS X with Apple Mail (however, I don't think the e- 
mail client could have anything to do with this). The other thing  
that sometimes causes problems is the weak inequality sign: <=  and  
in this case converting to InputForm does help. I sometimes forget to  
do this because after pasting the TraditinalForm of weak inequality  
into Mail it continues to look fine. However, in the case of Greek  
symbols there is no other choice that I know of but replacing them by  
Latin letters. I believe that doing this is up to the original poster  
of a message and not up to people responding to it.
