How is it that I successfully sent an email yet have no record of it anywhere?!
It is possible that the server sends the message, but is not creating a copy in the Sent folder.
Go to Menu > Accounts and see if there is an option in the General tab to save a copy of sent messages to the Sent folder. If there is, tick it and click on Save & Close.
Yes thanks: it says save a copy.
It was just that one email!
