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 ?
qmail 1.03 with SPAMCONTROL stunnel 4.43 running on FreeBSD 8.0-RELEASE
Config file: ; SMTP SSL (SMTP-AUTH) debug = 7 foreground = yes syslog = no cert = /usr/local/etc/stunnel/stunnel.pem exec = /var/qmail/bin/qmail-smtpd execargs = qmail-smtpd /mailhome/bin/vchkpw /bin/true
Thanks in advance !

I can't speak to your peer disconnection issue, but the byte counts pretty much mirror what I see from day-to-day. I looked in the documentation to see if I could find out how the byte counts are generated, but I was unsuccessful. In any case, here are the last 3 closures from my log:
2012.01.18 17:40:09 LOG6[320:3332]: SSL_shutdown successfully sent close_notify alert 2012.01.18 17:40:09 LOG5[320:3332]: Connection closed: 1526 bytes sent to SSL, 24149 bytes sent to socket 2012.01.18 17:40:50 LOG6[320:2688]: SSL_shutdown successfully sent close_notify alert 2012.01.18 17:40:50 LOG5[320:2688]: Connection closed: 126 bytes sent to SSL, 2797 bytes sent to socket 2012.01.18 17:50:36 LOG6[320:3412]: SSL_shutdown successfully sent close_notify alert 2012.01.18 17:50:36 LOG5[320:3412]: Connection closed: 1270 bytes sent to SSL, 121955 bytes sent to socket
