Reference: Stunnel Ver 4.31 Windows Binaries
This is the actual configuration file I am using. There is not too much to
it.
As shown below, this WORKS for Gmail's SSL port.. Port 465.
Notice that the sslVersion statement is remarked "out".
+++++++++++++++++++++++++++
output = STUNNEL.log
taskbar = NO
cert = stunnel.pem
client = yes
[SSMTP]
accept=DADSXPPRO:8025
connect=smtp.gmail.com:465
;sslVersion = TLSv1
++++++++++++++++++++++++++++
In theory (as I have read it...), to change this to TLS, I enable the
sslVersion line,
And change the port (for Gmail) to 587.
Port 587 and TLS for Gmail have been tested and verified via Microsoft
Outlook testing.
But when I do so, I cannot even log onto the Gmail server.
I get the error message referenced in the first message:
2010.02.25 10:35:44 LOG3[2696:2740]: SSL_connect: 1408F10B:
error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number
It occurs to me that I am only using the "stunnel.pem" file, as supplied by
the installer program.
Do I have a certificate issue?
