Hello, I'm using smtp-source as a test smtp-client and I've realized that it is not adding the "MIME-Version: 1.0" to the generated email. Hence, some email clients do not display the received message correctly. My suggestion would be to add the following line in the smtp-source.c file, in the "static void data_done(int unused, char *context)" function
smtp_printf(session->stream, "MIME-Version: 1.0"); regards, Jan
