Hi there,
Does the roundcube support to set up multiple folders to organise emails? having trouble with them. The emails don`t pop into the set up folder.
folders and filtering are 2 separate things. Roundcube has folder management functionality but this is dependant on server support of course.
Out of the box Roundcube has not filtering functionality built in, its a mail client and filter is best done on the server side. It does ship with the managesieve plugin which allows for management of sieve rules on the sever if that's something your setup uses. There are other plugins available in the plugin repo I believe.
