In Apple's Mail.App, can you reply with full headers?
For example, in Outlook (and most other mail software), replying will show you something like:
From: John Doe <firstname.lastname@example.org> Date: Monday, July 23, 2013 9:34 AM To: Jane Doe <email@example.com> Cc: Bob <firstname.lastname@example.org> Subject: RE: Test Message
Mail.app simply says the following - which omits the import details of who was cc'd etc:

I would much prefer Mail.app over Outlook 2011, but I'm trapped without the ability to maintain the thread of recipients in replies.
Surely there's some way to change this?
