I am using Zimbra Desktop 1.0 on Windows XP and have my yahoo small business mail account configured. But whenever I send an email from the Zdesktop it doesnt appear in the sent folder on the yahoo server. But when I send a mail using yahoo webmail the sent mail gets downloaded to the Zdesktop. So as a result I always have more sent emails on my Desktop than on the server. This problem does not seem to be there when I configured my free yahoo mail. The sent folder is always synced no matter what client I used to send the emails from.

Does anyone know why this happening and is there a solution?
