Right, I had done that:

Yes, I have protocol = pop3 and protocol = smtp; I’ve tried commenting them out individually, no change that I can see.

The doc really isn't clear about why you'd want/need these, by the way.

But your earlier suggestion (localhost instead of 127.0.0.1) seems to have worked. Still a mystery. I'll be tinkering on machine2 tonight, and then will try on the wife's machine!

protocol = pop3

The stunnel(8) manual has this. "protocol = PROTO application protocol to negotiate TLS This option enables initial, protocol-specific negotiation of the TLS encryption."

Is there any need for protocol-specific negotiation? Why? Stunnel provides a tunnel and POP3 works inside. That's all. Try the configuration without the protocol option.
