I posted a port for roundcubemail 0.1beta2 a few months ago; here is an update to 0.1rc1. There were a few enthusiastic responses; users should probably upgrade, as this fixes some SQL injection and XSS vulnerabilities, and is stricter about input validation in some places (other fixes include for PHP safe_mode and multibyte character sets).
"The Release Candidate number one has just been released. It includes a better and less memory consuming message parser and a neat integration of LDAP address directories. Also session authentication has changed to get rid of the annoying session- timeouts. The DB schema has changed slightly, scripts are provided for upgrading users to handle this.
