I setup a Linux email server. It is working as a pop & smtp & everything works fine. I can send & receive mail to and from firstname.lastname@example.org. What I want to do is host email for other companys. So I want to setup email for email@example.com, firstname.lastname@example.org, etc. Can this be done? How? Please Help. I would give 100000000 points if I had them. If i add john.com as an alias on my linux box, and point my DNS (john.com) to the linux box, it works, but under aliases I have only 4 lines. I know this must write to a file (I'm getting to aliases through linuxconf), where is it? I'm not even sure if this is the right way to do this and if there is more configuration needed, but it works. Please respond!!
