[stunnel-users] Windows Live Mail issue ?

[Victor]

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 LOG3[16954:34377572800]: SSL_read: Connection reset by

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

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
