Sent mail folder contents not visible

Sent mail folder contents not visible

Hi,
I am using the zohovo on a FC5[JDK 1.5] installation. I am not able to see mails in Sent mails and in Trash folders. I am able to create a new folder, move mails there and able to see it. I have also configured to store the sent mails locally[I have enabled that check box in mail options].
If there is any other configuration related changes I need to do please let me know.
