A company I worked for used Lotus Notes and Domino back in the day.
One day we got a mail sent to everyone at the company from the CEO, with some rather lewd content. As you can imagine it caused quite the stir.
As most here will know, SMTP by default doesn't verify sender. And the Domino mail gateway would happily match external addresses to internal accounts. The result was that it looked quite legit.
Turned out someone who was fed up with their job[1] had used this to appear to be the CEO, we have a 3 month notice period here in Norway, and well he got let go immediately...
Young me learned a lot about how mail worked thanks to that.
