Please follow the thread. He was getting a command error when connecting with pop3s. I gave him a stunnel configuration so that he could use wireshark to see what the command is. stunnel will do the ssl part, so he needs to connect to stunnel with pop3, not pop3s.
I have been, the whole thing. But I don't recall noticing you mention, anywhere, that you make an unencrypted connection to stunnel, and it makes an encrypted connection to the server under test, as a kind of proxy.
The same seems apparent in your most recent conversations with the original poster, too. Considering the steps you're, now, outlining.
