I don't know about Thunderbird, but my email client has a keystroke that does exactly that. I disable that feature though, because I don't like it; I very much prefer the two copies because I get the fastest one first (of course, I only receive one -- the system makes sure that the second one is not delivered to me but discarded silently).
I would be really annoyed if my mail system inflicted so much pain on my as Thunderbird seems to inflict on you.
