Hi,
Since our company had to migrate to Orange Office365 platform, we cannot send simple SMTP message using smtp.office365.com
We have to use SMTP over TLS.
While I have to use some applications which cannot use SMTP, I installed and setup STunnel.
When I try to send a simple mail like this : telnet myserver 25 ehlo ch-lepuy.fr mail from: [email protected]
I cannot continue with rcpt to syntax and I have the following message : rcpt to:530 5.7.1 Client was not authenticated
In the STunnel log file, I can see that : 2013.08.06 19:20:49 LOG7[1352:2832]: SSL state (connect): before/connect initialization 2013.08.06 19:20:49 LOG7[1352:2832]: SSL state (connect): SSLv3 write client hello A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 read server hello A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 read server certificate A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 read server key exchange A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 read server certificate request A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 read server done A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 write client certificate A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 write client key exchange A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 write certificate verify A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 write change cipher spec A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 write finished A 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 flush data 2013.08.06 19:20:50 LOG7[1352:2832]: SSL state (connect): SSLv3 read finished A 2013.08.06 19:20:50 LOG7[1352:2832]: 1 items in the session cache 2013.08.06 19:20:50 LOG7[1352:2832]: 1 client connects (SSL_connect()) 2013.08.06 19:20:50 LOG7[1352:2832]: 1 client connects that finished 2013.08.06 19:20:50 LOG7[1352:2832]: 0 client renegotiations requested 2013.08.06 19:20:50 LOG7[1352:2832]: 0 server connects (SSL_accept()) 2013.08.06 19:20:50 LOG7[1352:2832]: 0 server connects that finished 2013.08.06 19:20:50 LOG7[1352:2832]: 0 server renegotiations requested 2013.08.06 19:20:50 LOG7[1352:2832]: 0 session cache hits 2013.08.06 19:20:50 LOG7[1352:2832]: 0 external session cache hits 2013.08.06 19:20:50 LOG7[1352:2832]: 0 session cache misses 2013.08.06 19:20:50 LOG7[1352:2832]: 0 session cache timeouts 2013.08.06 19:20:50 LOG7[1352:2832]: Peer certificate was cached (6184 bytes) 2013.08.06 19:20:50 LOG6[1352:2832]: SSL connected: new session negotiated 2013.08.06 19:20:50 LOG6[1352:2832]: Negotiated TLSv1/SSLv3 ciphersuite: ECDHE-RSA-AES256-SHA (256-bit encryption) 2013.08.06 19:20:50 LOG6[1352:2832]: Compression: null, expansion: null 2013.08.06 19:21:13 LOG3[1352:2832]: SSL_read: Connection reset by peer (WSAECONNRESET) (10054) 2013.08.06 19:21:13 LOG5[1352:2832]: Connection reset: 65 byte(s) sent to SSL, 231 byte(s) sent to socket 2013.08.06 19:21:13 LOG7[1352:2832]: Remote socket (FD=316) closed 2013.08.06 19:21:13 LOG7[1352:2832]: Local socket (FD=244) closed 2013.08.06 19:21:13 LOG7[1352:2832]: Service [SMTP Outgoing] finished (0 left)
Here is my STunnel setup : client = yes output = stunnel-log.txt debug = 7 taskbar = yes
; Disable FIPS mode to allow non-approved protocols and algorithms ;fips = no
; ************************************************************************** ; * Service defaults may also be specified in individual service sections * ; **************************************************************************
; Certificate/key is needed in server mode and optional in client mode cert = stunnel.pem
; Disable support for insecure SSLv2 protocol options = NO_SSLv2
[SMTP Outgoing] protocol = smtp accept = 25 connect = smtp.office365.com:587
Does anyone have an idea ?
Regards?

Sure: https://en.wikipedia.org/wiki/SMTP_Authentication
In other words: stunnel worked fine and there is nothing you can do with stunnel to deal with your problem.

Hi Patrice,
Yes it is true, this is not a problem of stunnel. The problem is with your smtp dialog negociation.
you will auth to your server like this :
telnet myserver 25 ehlo ch-lepuy.fr auth login ... mail from: [email protected]
