The failures happen after several IMAP commands were already issued/answered in the session and not in an initial phase. Both the server and the client machines are virtual and in the same LAN and were moved around the physical machines just to exclude hardware issues. So can SSL_read() be called before the handshake is completed, i.e. in the "while in init" state? Thanks your answers!
