I have an existing mail server that I want to leave intact and simply put
a qpsmtpd server in front of it. This worked untill one of my users tried
to send an email from outside on the internet. Their client tried to do
smtp authentication and of course it failed because the server that is
capable of authenticating is behind the spam filtering server. My plan
was to use the username and password supplied by the client and then mimic
the client dialog to the actual mail server. If the actual mail server
responds with a successfull authentication then the front line qpsmtpd
server will allow the relay otherwise it will deny relaying.
The actual mail server uses a postfix vmail database on a mysql engine, I
didn't want to try to authenticate against it because if I get this "smtp
auth proxy" working then I can use it in other circumstances. One of my
clients is running netware for their email server, I don't know if it does
smtp authentication but that would be a good example of a situation where
you would want to use the existing smtp server for authentication.
