Hello, everyone. The firm I work for has a web development/hosting subsidiary. One of the services they offer is a POP3 mail server for some of the clients who host with us. It currently has around 250 domains on it, but the server is starting to feel the strain, so we are looking to replace it. It is currently an NT box, and we think a Linux box would be a more appropriate choice. However, my experience of setting up mail on Linux boxes has revolved around SLOX, and mulit-domain setups have been limited to aliases to the clients' main domains. So I am looking for advice on what to use to allow us to host multiple independent domains on a Linux mail server. Also, if anyone has any good FAQs or HOW-TOs, I would like to have them pointed out to me. I did do a Google search, but there was so much clutter it was impossible to find anything meaningful. The system also needs to be simple to administer, as the web guys are likely to have to do the day-to-day administration themselves. They're good web guys, but they aren't such hot admins. Maybe Webmin would be the answer to this part. Thanks, Stuart.
