I'm having a rather strange problem with mail.app (10.4.3 version) running on both of my macs right now. I have created an IMAP account, and gone through the process of assigning the sent, drafts, and trash folders to their respective folders that appear when I set up the account.
However, this little guy is still hanging around:
But there are no folders left, as they have been 'moved' to their correct locations. Any ideas as to what is causing this, or if there is a way to fix it?
