Well, I stumbled across an interesting easter egg in Mail.app (1.3.3) I was testing out an email form for a client of mine and instead of using my email address, I was randomly typing in fake addresses. On the last test I conducted, I sent the email form with a return address of: email@example.com I received the email in Mail and there was a picture in the top right corner! This is DEFINITELY not someone in my address book. I wonder how many more of these are buried in Mail? Does anyone know how to find out? I've attached the image to show you what I mean. Can anyone else recreate this?
