As you since realised, Marc suggested full emails. Personally, I'd not share even subject lines. I'm trying to make it as difficult as possible for people to glance at mail going through my mail servers, using TLS et al (both opportunistic and forced, if I know my partners offer TLS as well) and S/MIME or GPG-encrypted emails when possible. I'd *never* send any data to Joe Random Service for scanning, even it was a free service. If the NSA or anybody else wants the data, they can bloody well work for it.
