Zimbra is an opensource desktop application software . Its for GNU/Linux and Mac OS from Yahoo . Zimbra is another Yahoo company one like the delicious book mark management . I was using Mozilla Thunder bird , but when I saw Zimbra with much more features than that , I thought of trying it . Yes its having nice features, I love the look of it. Its based on the Mozilla . Some of the features are having calendar in it . So we can organise calendars , check emails whether its Yahoo, Gmail , MSN , AOL , Zimbra, Hot mail or any from it . You can check your flickr images from Zimbra. There is a slight problem with Zimbra connecting to flickr . Though Zimbra is a yahoo company its having trouble getting pictures from the flickr ( run by yahoo itslef ). The screen shot is shown here to see how it looks . When we try to check the flickr pics, it asks for authentication and we can authenticate to our yahoo account . We can upload pictures from the new window , but I don’t find a scroll bar to scroll down . We can use the Tab to got to the submit buttons . I don’t know whther yahoo have tested this in Ubuntu . Also don’t know whether the issue is only for me . Another one is it creates a short cut to start Zimbra desktop . But icon is not appearing and also asks whether we need to run it . The screen shot of trying to upload pictures through Zimbra is below.
