This webmail client software can be installed on variety platform like Windows and Linux. Plus more, it support various email technology like IMAP/POP3 mailboxes, and an optional email-server mode that uses Exim as the MTA.

Personally I have used the Squirrel mail, Round Cube and the Atmail on Xampp platform.I was successful in installation with the above with the mercury mail server in the concerned organization. Actually if Appearance is to be consider the Atmail is the great one,

if you consider installation procedure and all, the roundcube rocks.

But if functionality is considered then only and only squirrel mail.

It has useful plugins an d is open source and very easy for adapting the same for the organizational alteration and great customization to the interface.

You only require some knowledge of the CSS style sheet for the customization and understanding of the code with the squirrel mail.So if you value the functionality with no fancy features go for the Squirrel Mail.

I have not used Zimbra nor the Xuheki for any comparision.
