I’m pretty new to email servers, but have sort of an odd question. My company has an exchange server and the “powers that be” want to put it on the net as an SMTP server. Knowing Exchange’s track record involving security holes and virii and spam,along with the stability and security of NT, is there a way to say setup a qmail or sendmail server (running Linux, or *BSD) for the internet mail and relay all of the messages to the exchange box and vice versa for outgoing mail? I don’t have a speedy machine left for this, so I was thinking about qmail for the server (since everything I have read about claim that it is speedy) but couldn’t find a FAQ on how to relay a message between servers (the exchange part I’m not too worried about), butfor the qmail/sendmail server, I have set it up just listening to localhost and as a POP server (internal), but not sure about the routing of email between servers.
