A couple of lifetimes ago, when I was a videogame developer, we were having issues with a publisher. I sent them an email explaining why I felt that a certain situation was unfair to us, etc, etc. A few minutes later I got an email from the producer, but obviously intended to be read by one of his colleagues, who I had CCd on my email. It said something to the effect of "you know, they kind of have a point, blah blah" This was almost immediately followed by a plain-text email that said "recall" IIRC. I assumed this is how Outlook implements recalling an email internally, except that I was using some Linux email client that was blissfully unaware of this. I chuckled. Just seconds later yet another email begging me not to read the original email as it had been sent by mistake, apologies, etc. I guess the moral of the story, if there is one, is that you can't really un-deliver a message once it has been delivered. Think twice before you send!
