Sded, thank you for summing up by using your conditions as an example. You’ve provided other useful information, too:
Outlook Express doesn’t distinguish SSL from TLS in its settings. (You don’t have to define the type of the secure connection you use.)
Thunderbird distinguishes SSL from TLS in its settings.
Stunnel distinguishes SSL from TLS in the stunnel.conf file.
As I said in my previous posts, if you use Stunnel, you need to define “protocol” for the TLS connection, but shouldn’t for the SSL connection in the stunnel.conf file.
