Hello,

I have successfully used stunnel with blat to send e-mails from my gmail accounts. Getting this to work with my new internet provider "Ziggo" in The Netherlands seems impossible, despite days spent on the internet searching for help and trying numerous configurations. Whatever I do, there is always this message: SSL_connect: 1408F10B: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number

Any help would be highly appreciated.

Pieter Verberne

PC: i7 OS: Windows 7 - 64bits Stunnel version: 4.53

When sending an e-mail from my PC with Thunderbird 2.0 I can successfully use TLS but not SSL. My provider says about secure smtp connections on their website: Outgoing mail server smtp.ziggo.nl (port number 587) Use of SSL (Secure Socket Layer) / TLS yes For this server is verification required / identity check yes User name your e-mail address Password your e-mail password

Stunnel.conf: # GLOBAL OPTIONS

debug = 7 output = D:\Pieter\Temp\stunnel-log.txt fips = no cert = stunnel.pem

# SERVICE-LEVEL OPTIONS

[SMTP Ziggo] client = yes options = NO_SSLv2 options = NO_SSLv3 sslVersion = TLSv1 accept = 587 connect = smtp.ziggo.nl:587
