I'm new with stunnel and I'm experiencing a issue. Windows Live Mail is closing the connection with the SSL tunnel without send the close down packet, resulting in connection reset by peer. Follow the output debug of stunnel:
2012.01.18 17:13:25 LOG7[16954:34377572800]: Socket closed on read 2012.01.18 17:13:25 LOG7[16954:34377572800]: Sending SSL write shutdown 2012.01.18 17:13:25 LOG7[16954:34377572800]: SSL alert (write): warning: close notify 2012.01.18 17:13:25 LOG6[16954:34377572800]: SSL_shutdown successfully sent close_notify 2012.01.18 17:13:25 LOG3[16954:34377572800]: SSL_read: Connection reset by peer (54) 2012.01.18 17:13:25 LOG5[16954:34377572800]: Connection reset: 293 bytes sent to SSL, 1293 bytes sent to socket 2012.01.18 17:13:25 LOG7[16954:34377572800]: Service stunnel finished (0 left) 2012.01.18 17:13:25 LOG7[16954:34377572800]: str_stats: 28 block(s), 988 byte(s)
The e-mail message is sent successfully but Im very intrigued with the line "Connection reset: 293 bytes sent to SSL, 1293 bytes sent to socket", that make me think that some data was lost in the middle of the connection. I need to fix something or this is a normal behavior ?

Thanks in advance !
