Auto forward won't work

Hi,

I'm using Zimbra Desktop, and I want to forward all of my e-mail to another mail: xxx@hotmail.com. So i did the following: under preferences --> mail --> I've selected "When new mail arrives in any folder (excluding Spam and Trash)" forward a copy to: xxx@hotmail.com, and it's works fine. The problem occurs when I close ZD and restart it, then the option selected isn't "When new mail arrives in any folder (excluding Spam and Trash)" anymore, but "Only when new mail arrives in my Inbox" instead. This happens every time I restart ZD. Any ideas??

Thank you,
Bobi
