Not allowing me to delete queued messages

Binary package hint: evolution

Because I typed in the wrong e-mail address 3 times, it keeps trying to send it. Everytime I quit, it tells me i have unsent messages, and asks me if i'm sure I want to quit. OF COURSE I'M SURE. How can I make evolution stop wanting to send these messages?!
