Mail Server for Multiple Hosting Clients
I am setting up a web server for the company I work for. We plan to be hosting multiple domains for different companies.
In the standard hosting package, email is almost always included. I have run a PostFix mail server for 1 domain for a few years, but I have never attempted to run multiple domains from the one server.
I have read in other posts about virtual hosts and I tihnk I understand that concept. What I would like to know is how other people in my situation manage their email service?
