https://emailprivacytester.com/ https://emailprivacytester.com/ is great. They'll send you an email with dozens of tests to determine what kind of information your mail client (MUA) is leaking to senders. I use mutt exclusively and of course it's perfect. When I first tested emailprivacytester.com, I also checked Mail.app on OSX ~10.7, and iOS ~5, and I was quite happy with the results. Now, I always check settings immediately after launching any app for the first time (and on OSX always run Hands Off!, which I greatly prefer over Little Snitch), so it's possible that I fixed obviously-bad defaults before getting bitten by them. Unfortunately, I'm not sure what the author is trying to say -- is Mail.app worse in Mavericks, or has he just not bothered to configure it sensibly for his (our) uncommon usage preferences?
