Does DMARC have to be specifically setup by a domain admin ? i.e. it can't 
just be inadvertently turned on.

I presume it does based on what I read briefly, about adding entries into 
the domain records etc. I have to admit until I read about it on this list 
I was almost fully clueless as to what DMARC was (acronyms to the ignorant 
and all that).
