I’ve recently realized that making it too easy to send email is a bad thing. For the longest time, I thought that any mail program that didn’t have a key shortcut for sending an email was broken. Now I have seen the error of my ways. I’ve gotten in the habit of using Apple Mail in Offline mode so that it doesn’t send the emails until I return to Online mode. Apple Mail always tries to second guess me on this, which is a constant agravation, and then came the biggest affront: the Outbox disappeared comletely! ARG! Normally, when you are in Offline mode and you send email, the Outbox shows up and will stay there until the email is sent. That is nice, and useful. But recently, for whatever reason, the Outbox never came out anymore. What a pain… go after some searching around and reading of the ~/Library/Preferences/com.apple.mail.plist , I found this forum thread to set DisplayInThreadedMode to no in order to permanently hide the Outbox. It turns out mine was set to no already. I switched it to yes and voila! I had a reappearing Outbox again! Yee haw! Now WTF does “Threaded Mode” have to do with the visibility of the Outbox?
