Ok, I have a little linux experience, I've setup a web and FTP server on a Mandrake box before. Bassically I have an old Pentium 200mhz and I have Mandrake 10 installed on it. I want to install a Mail server on it. IIRC I installed all the optional servers when I installed the OS, so I should just need help configuring what ever is installed by default. The reason I want a mail server is I have a yabb forum and a Gallery 2 running on my webserver and I want to be able to send mail from them. Also I heard that Comcast blocks the Mail port for security reasons, If so should I try a different port? Any help would be greatly appriciated.

If that is the case, you are SOL. Changing the port will not help you because internet mail is sent via SMTP and that is port 25 TCP period. You can change the listening port on just about any MTA, but getting mail in and out will be problematic because everyone else is set for port 25.

What happens when you type "telnet mx2.hotmail.com 25" ?

Do you get a response like :
Hotmail's mx2.hotmail.com said:
220 bay0-mc10-f15.bay0.hotmail.com Sending unsolicited commercial or bulk e-mail to Microsoft's computer network is prohibited. Other restrictions are found at http://privacy.msn.com/Anti-spam/. Violations will result in use of equipment located in California and other states. Sun, 5 Mar 2006 16:31:43 -0800

Or does it time out? If it times out, chances are your ISP is blocking outbound SMTP to destinations (except for their own mail servers) for security purposes. If you cannot connect to foreign machines on port 25, you are, unfortunately, SoL for a mail server. :( Changing ports will do absolutely no good.

However, if your ISP has an SMTP server to use (and virtually all of them do) set up a mail server but configure it for a "sattelite" system where any mail is relayed through your ISP's mail routers and not your individual box.
 
I got the same thing you did when I typed the command. So I'm guessing they do not block the port. So bassically how do I go about setting the thing up? I really don't care about any special features or anything I just want to setup mail server for my forum. So where do I start :).
 
Pick a MTA program (I use Postfix) but any of them work. Postfix is fairly secure, simple to install, but isnt as light as other MTA's. My mail server only handles a couple hundred messages a day, so it really doesnt matter. If you intend to do several thousand, I'd use sendmail, however, you better not be, I dislike spammers. :p

install postfix and config it. Points to keep in mind: Secure the damn thing. You do NOT want a nasty-gram from your ISP tracking you to an open relay box....

Read up on how to close any open relays on the box. Keep in mind that unless you have a static IP or some sort of dynamic DNS, a TON of your email will be rejected.
 
Well so far I've gathered that Mandrake has postfix installed by default. All I want to do is do the minimal config to get email sent from my forum. I've been google'ing my ass off and can't find what the hell I need to do. I'm guessing there is something in the config file I need to change but I'm really not sure what. Man I h8 linux...
 
Comcast does not block the port.

also, I used qmail

look at qmailrocks.org if you run out of options. step by step instructions.
