That question is not easy to answer without knowing more about the 
complete setting. What kind of mail server do you use etc. ....

I personally would never assume that there is no reason to authenticate 
local email, only because the sender is "saying - I am 
"www-data.domain.tld".

I am sure that there are suitable plugins for wordpress which are able 
to use smtp-auth - another workaround could be to use a function to do 
the same.
