I'm using stunnel as a reverse proxy. I have an smtp server smtp1 and an stunnel server proxy1. Clients connect to and negotiate ssl on proxy1 which then connects to smtp1 via a plaintext connection. stunnel does not reside on the client. If I connect the client directly to smtp1 via ssl it works fine.<br>

Hmmm if you are using stunnel on client side (as suggested by your
correction) it is that YOU DO NOT WANT TO USE SSL OPTION in OUTLOOK.<br>
<br>
because stunnel will act as an "almost transparent' ssl tunnel. <br>
<br>
So in outlook : uncheck ssl option and give "localhost" as your smtp
server.<br>
<br>
and adapt local port according to your stunnel conf.<br>
<br>
Apart from that : I use stunnel on the server ONLY, with self signed
certificate coming from openssl, <br>
and outlook configured as ssl client is working.<br>
SSLversion = all is always GOOD<br>
<br>
works with stunnel 4.20 on linux mandriva 2008, outlook 2007<br>

I am trying to setup stunnel to ssl proxy mail to an smtp
server and this seems to work fine for thunderbird but when I
try using outlook 2010 to connect via ssl I get the error:
<div><br>
</div>
<div>Send test e-mail message: Your server does not support
the connection encryption type you have specified. Try
changing the encryption method.</div>
<div><br>
</div>
<div>For sslVersion I have the option of SSLv3 and TLSv1, all
and SSLv2 do not seem to work so I'm not sure if that is the
problem</div>

<div>Anyone else run in to this or know what I might do to
resolve it?</div>

<div>I can get it to work if I setup ssl on the end server
directly and bypass stunnel
