I suspect the draft is also not in the Gmail server. This is probably 
because you still have the email address listed in the IMAP settings of 
the other account (essentially having the same address in two 
locations). If you change this then it requires that the Gmail SMTP 
server allows you to use the other email address as sender. I'm not 
quite sure what the current policy is, but I've had reports about it 
changing the sender automatically.

Another option is to leave the accounts as they are now and then add a 
rule to the “Sent Messages” mailbox of the non-Gmail account which 
simply moves the message to the Gmail account. This way the header 
information of your messages also won't reveal the use of Gmail.
