configure sendmail

I can't seem to find any information on how to configure send mail. All I want is my server to allow connections on the smtp port and relay mail. (it's a LAN server and can only be accessed by being physically in my house so spammers is not an issue).

Sendmail is running but not accepting connections, if I telnet borg 25 it can't connect. (borg is the server name).

Also, I'd like to be able to access mail from root using pop3, is that possible? If yes how do I configure that? Thanks in advance!

It apears to be listening locally but not externally. It's probably blocked by the firewall but I don'tknow how to use the firewall in linux, can someone show me, or just tell me how to disable it? I used the GUI option in red hat but everything I change it nothing happends, it goes back to default.

webmin

install and configure that to gain access to a GUI for all your computer services, hardware, boot, etc.

IIRC ports for mail are 110 and i forget the other 115 or something like that.

Thanks for that tip, I installed it and the smtp options are working, I'm just not understanding what exactly I need to change for it to work. Most of the options I have no clue what they do.

Bu this sure beats trying to find and edit ackward config files!

Bump, still can't figure it out. I can't even send mail from within the server, it does not seem to resolve the domain names of email addresses.

Even after adding my network PCs as trusted, I still can't connect to the port 25 at all.

when I try to send mail with the php mail() function, I get an email like this that goes in the root account:

The original message was received at Mon, 12 Apr 2004 16:05:49 -0400
from localhost.localdomain [127.0.0.1]

----- The following addresses had permanent fatal errors -----
<webmaster@iceteks.com>
(reason: 550-Verification failed for <nobody@localhost.localdomain>)

----- Transcript of session follows -----
... while talking to iceteks.com.:
>>> DATA
<<< 550-Verification failed for <nobody@localhost.localdomain>

<<< 550 Sender verify failed
550 5.1.1 <webmaster@iceteks.com>... User unknown
<<< 503 valid RCPT command must precede DATA

It sems that it can't resolve outside sites or something, is there a way to fix this?
