I'm using Roundcube Webmail from last 2 year. Recently I updated my Roundcube Webmail version. When I go through the Roundcube Webmail Forum I got to know there is mobile skins are available which are compatible with latest version of Roundcube Webmail. I purchased Royal-Blue Mobile Roundcube Skin from www.roundcubeskins.com. Awesome work done.

Convenient Web-GUI for mail. It is possible to configure the interface for each user. Easily work with plug-ins. Fast, beautiful, high-quality product that will appeal to all at once on the company.

Very easy web mail, fully featured. One of our users said that it was the best webmail he'd used, after Googlemail. It does require an IMAP server with no additional folder prefix (We upgraded to Dovecot at the same time as we upgraded from IlohaMail to Roundcube), but the transition was smooth, and as long as you meet the minimum requirements this works very well.
