So, possible? I have an older brother MFC-8840D with a scan to email function. It's old enough that it doesn't support smtp authentication or ssl. I'm fairly sure I can configure stunnel to forward a connection and add on the ssl function, but anyone think it would be possible to use smtpauth (tiny program originally meant for outdated email software clients) in combination with stunnel?
My issue is i can't figure in my head how to configure it all. As far as I can tell, my printer will only take an ip address for the smtp server and defaults to port 25. The smtpauth software seemingly only takes inputs sent to 127.0.0.1:25 on whatever machine you run it. If i set the ip on the printer to the machine hosting the service , will it take that input? Then I could set Stunnel to accept anything on a specific port or ip so it seems a bit more workable, but I'm not sure of the logistics of how to point one to another if I'm running the services all on the same machine.
