Hi there, I have just upgraded my server from Ubuntu 18.04 to 20.04, everything is working fine except that at my Squirrelmail interface I get this error: ERROR: No se pudo completar la solicitud. Respuesta desconocida del servidor IMAP: 1.* OK [ALERT] Message 1 appears to be a Unicode message and your E-mail reader did not enable Unicode support. Please use an E-mail reader that supports IMAP with UTF-8 (see https://tools.ietf.org/html/rfc6855.html) I've been looking around and I tried solutions for curier which is my imap server, but the problem seems to be in squirrelmail...
