Have you looked into you outbox, I have had them saved there for some
reason or another at times. If the message is there and you feel
uncomfortable about it, do what I did and just move that puppy on over
to the Drafts. Don't do what I did and forget that it's there in Drafts
though as I tried to find the email that I recently sent to the Drafts,
I found one email that I missed finishing to send to my Dad for the
idea that he could Machine embroidery the Hogwarts patch for his
Grandchildren for Christmas and I would knit some Harry Potter Scarves
for them. *sigh*
