Stop Microsoft users sending 'reactions' to email by adding a postfix header

Oh good emails now have that iPhone ass:

    
Liked "The entire message I just sent repeated back to me because this fucking iPhone user can't be assed to use their goddamn words or even just do a regular emoji because it's two extra fucking buttons."

  

I miss emoticons (in fact I never switched :D), and just when I'm getting used to emojis they added this reaction shit, and now they're expanding that horse fuckery to email. Woo hoo.
