While searching for SquirrelMail themes and plugins I stumbled across RoundCube. RoundCube is essentially a nice looking opensource webmail interface full of AJAX goodness. I probably won’t start using it until there is some decent search functionality – because I have thousands of emails sorting and searching is all that really matter. So this is not for me just yet but promising… and probably inevitable. In the meantime I will just put up with SquirrelMail.
After squirrel trials on a few domains I came across roundcube only yesterday and installed it to two customer sites who want webmail without any trimmings. They adore roundcube!
