Sure. thats a really good hidden service, 

As sender ..
- i don't know where the server is, and who its operating..

As receiver
- i see a open relay ..

As user
- is send a mail, and someone alters it, because he feels it rights.. or
	thinks its "the best" todo

Its truly the best combination of all Tor can provide.
