Gmail uses SSL on port 465, as shown above.

Gmail also listens on port 587 using TLS, which is purported to be more 
secure than SSL.  The snippet below comes from my stunnel.conf here at home.

        CAfile = cert.pem
        cert = client.pem
        client = yes
        RNDfile = .rnd
        sslVersion = TLSv1
        fips = no

        [gmail smtp]
        accept = 27
        connect = smtp.gmail.com:587
        protocol = smtp


To use stunnel for SSL/TLS support, as required by Gmail, you would tell 
Blat to use IP address 127.0.0.1 as the SMTP server, and the port number 
should be what you have in your stunnel.conf file.  The IP address is 
important, because it tells Windows to send the internet request to the any 
program listening on your port in your computer.  If your stunnel.conf file 
looks just like mine above, then you would want to use "-server 
127.0.0.1:27" on your command line to force Blat to use stunnel for 
providing TLS service to Gmail.
