Checking Gmail through Zimbra

[msl278]

Hi, is it possible to check my Gmail inbox and Yahoo inbox in my Zimbra account? If so, can you please point me to a source that shows me how to set this up. Thanks.

Preferences tab -> Accounts sub-tab -> Add External Account button.

Is there a way to just preview emails through Zimbra? I did this and Zimbra ends up downloading all my headers from 2005 and takes up space. Would prefer some kind of preview function--is it available through a Zimlet? Thanks.
