Im sorry..im very new to this "linux" world, I have cable modem, Do i need to buy a dns? I will really apreciate if you can help me just to start making the mail server to work..I can send emails but I cant receive any. thanx a lot
Do you have a registered domain name? If so, you need to go to you registrar and create a dns "A" record for you mail server. All this does is point mail.yourdomain.com to you ip. Then you need to create an "MX" record showing that mail.yourdomain.com handles all the mail for yourdomain.com. If you don't have a registered domain name you can't receive e-mail because of the way smtp works. You can send because sendmail sees you isp as part of the return address but nobody can reply to it.
You might want to peruse the linux documentation project website:

Hey guys thanks a lot for all the info, Im getting it =0P..Let me ask you something, I have a Linksys router, and obviously is using my wan IP would that interfare w/ the Mail Server? (im saying this because if I put a WEB SERVER people wont be able to see it because the router its using the wan)
thanks again
thanks again
Check the documentation for your Linksys router, specifically for something like "virtual server" setings. This will let you open up a specific port number and supply an IP address for the service. In this case, you want to open up port 25 and set the IP address to the local address of the computer you have your mail server running on. The modem/router will now forward any incoming smtp (mail) connections to your local server.
The previous comments about setting up a DNS server for your domain also apply. Generally, this also means you must have a fixed IP address (for your modem) so other computers on the Internet will know how to reach your computer and that it won't be changing all the time.
