As it is highly requested that a mailuser interface has to be made. I would like to code one for Roundcube, furthermore extending the roundcube addon for ISPConfig to a full mail user interface and also a version for the Squirrelmail. I know it wouldn't be a mailuser interface in ISPConfig, but wouldn't it be better when the mailuser just has to know one url where he can check his mail and change his settings? When that would be fine i would start pretty fast with the addons. @ISPConfig team Will the Remote API and the package system be finished with the new ISPConfig 18.104.22.168? PS: If somebody wants to help, just contact me.
