I'm looking for a Linux-based POP mail proxy to put in my company's DMZ to field requests from sales personnel running POP clients on the Internet. The mail these folks need would be on a MS Exchange 5.5 server, inside on the LAN. I don't want to open ports on the firewall directly into the Exchange server - rather, I want to add an extra layer or buffer of security between Exchange and that big bad Net (and I'm not confident it is a secure enough product anyway). So I'm wondering if qpopper can fill the bill. I would need to have qpopper use my internal Active Directory to authenticate users, and allow them to pick up their POP mail from the Exchange server. Has anyone done a config like this, or can anyone offer suggestions on using qpopper in this way?
Thanks much! Scott Henderson
