Weird Yahoo mail issue
 

Wife and I have identical Moguls. She has an IMAP Yahoo email account. and I have a POP account. Both send and receive fine, but her sent items all disappear from the sent box. Her IMAP account auto-configures to use a Yahoo server to send, and my POP account has to be set up by hand to use the Sprint server.

Any clues?

Yahoo IMAP
 

I have my Yahoo mail account setup as imap on the phone and I can see all my folders and am able to transfer my incoming mail into the appropriate folders but once it syncs i cant see any of the mail in the folders.
