Mac OS 10.6.6 Mail 4.4 Sent an email to someone with other people listed in the BCC field. All good. Forwarded that email (from my sent folder) to the original recipient sometime later asking for a response as I hadn't had a reply to the original - the recipient saw the original BCC field with ALL people the original email was BCC'd to. What a joke. Just tested the same with Lotus Notes, no problem. The BCC field wasn't visible even on the forwarded email.
