Hello! I'm running Courier-Imap (+qmail+vpopmail (no *sql)), but I have problems with creating new boxes in roundcube and with Czech special chars in names of boxes (like ěščřžÃƒÂƒÃ‚½ÃƒÂ¡ÃƒÂÂé). But if I try your demo, all goes OK. What IMAP server are you running under the demo? Thank for your answers.
