I'm negotiating with a difficult person via email and am interested in whether they have anyone bcc'd on the emails they send me. I know what bcc is (and therefore know that if someone is bcc'd on the emails coming to me I won't be able to see who it is) but just wondered if there is a way of telling from the properties whether the exchange is just between us or whether someone else is secretly being bcc'd on the emails I'm receiving. A friend mentioned several years ago she colour coded her emails and could tell if someone was bcc'd becuase the email would be coded to a different colour from one without a bcc. I would love to hear if anyone does know a way of colour coding or knowing what to look for in the properties to spot a bcc email - and whether this can be applied to emails already received. Many thanks
