I tried to give my username/password in the session and in the transport, but the error still theire.
I'm not even sure this cause the probleme
could you help me.       

here is the code

mb.setExpeditor(vmime::mailbox("me@somewhere.com"));

                vmime::addressList to;
                to.appendAddress(vmime::create <vmime::mailbox>("my_username@free.fr"));

                mb.setRecipients(to);

                vmime::addressList bcc;
                bcc.appendAddress(vmime::create <vmime::mailbox>("you-bcc@nowhere.com"));

                mb.setBlindCopyRecipients(bcc);

                mb.setSubject(vmime::text("My first message generated with vmime::messageBuilder"));

               
                mb.getTextPart()->setText(vmime::create <vmime::stringContentHandler>(
                        "I'm writing this short text to test message construction " \
                        "using the vmime::messageBuilder component."));

                // Construction
                vmime::ref <vmime::message> msg = mb.construct();

                vmime::string msgTxt = msg->generate();

                session_out->getProperties()="my_username";
                session_out->getProperties()="my_password";
                session_out->getProperties()=cServerOutName;   /* init = smtp.free.fr */

                std::string std_str  = "smtp://";
                std_str += cServerOutName;  
//               vmime::utility::url url( std_str);
                vmime::utility::url url( "smtp://my_username:my_password@smtp.free.fr");
                vmime::ref <vmime::net::transport> tr =
                                session_out->getTransport(url);
            //    tr->service::setProperty("options.need-authentification",true);
                tr->service::setProperty("auth.username", "my_username");
                tr->service::setProperty("auth.password","my_password");
                tr->connect();
                tr->send( msg);            <-- execption is thrown here
