My understanding is from my quick search on this topic is that IF you setup an open relay then that relay can be used regardless of the connection coming through a SSL encrypted connection or a plain-text connection on port 25. Plain-text (25) or encrypted (465) has nothing to do with authentication, just like you can visit many websites using http (80) and https (443) without actually logging in. I am not sure having them open by default would be a good thing. |
