I really don't know the answer to that question. The scenario is that
they run a django based web app, and they wanted me to add a password
recovery feature to it. When I did that, and it tried to send the
recovery link to the user, it failed with 'SMTPServerDisconnected.' I
thought, of course, there is no SMTP server running, so I set upon
getting postfix running. As I said in my initial post, I've never done
that before. I'm a developer, not an admin ;-)
