RedHat Linux 7.2 Email Server

[mtesta1214]

Ok, How do I set up the Linux box to be an email server. I have DSL, and am behind a D-link router/firewall. I can send email from the server locally or remotely(telnet), but I cannot recieve email, and the address on the emails sent out is just the 'computername.workgroup'

What do I need to do to setup the Server to recieve email.. also what ports will I need to open on the Router/Firewall... Will I need to open ports 110, 80, and???etc???

Thanks in advance.

you might want to get a more recent version of redhat (like 9), because it's a lil easier to configure this stuff. for the mail server, you'll need the mail server tools (you pick them when you install redhat), as well as opening ports 25 and 110 (although you can change these, especially if you use secure services -- which is reccomended).

most importantly, the biggest thing you need is a dns presence, meaning you need a domain name registered and you need the dns point your domain to your ip address of your dsl connection, but BEWARE that more often than not doing this VIOLATES the terms of your isp's terms of service, and your service can be suspended or terminated for running your own mail server.

that said, you can get all kinds of information about running a server from redhat directly. they post all their books and whatnot online. you can get information for redhat 9 here

Above everything (except for your ISPs terms of service).

Learn how to properly secure it. It is quite easy to make a mail server work. But you must make sure that it is setup to not relay mail. Spammers will find you and use your mail server to distribute their spam. Open relays are EVIL EVIL things.

And a newer distro would be easier than 7.2 and more secure out of the box. There will actually be 2 servers to setup. SMTP which sends/recieves mail and operates on port 25. Then you will need POP or IMAP to allow users to pickup their mail they operate on 110 (POP3) and 143 (IMAP).

If you plan to do webmail you should look into only doing it via SSL and use 443 so passwords are encrypted.

You should also do some reasearch on what mail package you want to use. There are several options out there. RedHat uses Sendmail by default.
