How do I fix my email messages from getting stuck in drafts

I have two email addresses linked to the same yahoo mail account. On my Motorola Razr Droid M, suddenly I'm only allowed to send messages from one account. Everytime I compose a message from my business account, press send, then it goes into my draft folder and stays there. I have already tried clearing cache, date, and deleting and reinstalling the app. Same issue. Please help.
