I have a small network and a broadband connection. I am using SMC Broadband router and NAT is enabled on it. I have a website which also has my mailserver(Somewhere in US). I wish to set-up a mail server in my home and use it to communicate for internal mails sent to each other. also, I have mail accounts set-up on my site for each member. I need help in configuring fedora server for using it as main DNS / Mail server in my local PCs. All PCs in my home will use local linux (Fedora) for sending / receiveing mails using a dummy domain name like megastar.com which is not registered. Also, I want sendmail to get mails from each account on my webserver and put it in respective users mail account on this server. Can anybody help me in configuring fedora for this?
