1. get the MTA (sendmail, postfix,qmail,exim), but i suggest you to use postfix, it is easy to configure and secure.
2. install the MTA.
3. configure the MTA.
4. try to telnet localhost 25, and see whether it get response or not.

but you try this web www.tldp.org, and search for postfix documentation.

Hi

What is MTA?, by default sendmail has come with redhat 8.0, what next, when i did telnet localhost 25 and also 110 i got messg saying unable to connect, connection refused.

MTA is mail transfer agent, such as sendmail, postfix, qmail.
if you do telnet localhost 25 and get msg unable to connect, its mean that your sendmail haven't running, just do the following "service sendmail start" in your redhat command prompt, then try to telnet again and see whether get a good response or not!

after that get your redhat's cd and put it in your cdrom and install the rpm for imap.
then do telnet localhost 110, and see whether you get good or bad response.

After that tell me what happen and i will try to help you to setup a basic mail server.

HI Joseph,

after starting sendmail service i tried telnet localhost 25 and i got this response

220 localhost.localdomain ESMTP Sendmail 8.12.5/8.12.5; Thu, 4 Sep 2003 13:47:33
+0530

earlier i was getting connection refused.... messsg now i will add imap from redhat cd and let you know the status. Is the above messg okay with localhost 25??
thanks

yes very good, it is good response.
i think it is better for you to upgrade your sendmail to 8.12.9 because you are using sendmail 8.12.5

joseph tommorow shall i install imap and update u?, tomm will u chk and getback to me? thanks

yes, i will online every working day (mon-fri) except saturday and sunday.
i will follow your thread.

Hi Joseph, when i did rpm -qa imap it is showing imap-2001a-15
and it is located in imap: /usr/include/imap, what next ??, can we do with pop instead of pop?

ok try, do telnet localhost 110
and see what the response,
if the response say unable to connect you must do it manually in /etc/xinetd.d/ipop3 and change disable= yes to "no" and restart xinetd using /etc/rc.d/init.d/xinetd restart.

Hi joseph, i did disable=no and restarted xinetd and then when i tried telnet localhost 110 iam getting good responsr here is the o/p :- +OK POP3 gbs v2001.78rh server ready, what next... thanks for all ur help ...

ok, let go on

next go to /etc/mail and edit file sendmail.mc, find 127.0.0.1 and change it to 0.0.0.0 save it and do the following command m4 sendmail.mc > /etc/sendmail.cf and then restart ur sendmail using service sendmail restart.

Then go to /etc and edit sendmail.cf find the word Cwlocalhost to Cwabc.com or whatever your domain. (remember there is no space between Cw and your domain), Restart your sendmail.

Try to add some user into it using useradd xxx then passwd xxx

Now you can try your mail server in your client computer such using outlook express or whatever.

I think your mail server is ready to send and receive an email.

Hi Joseph thanks i will try this right now and post u, before this, when i tried from windows machine telnet ip-address ( of my redhat where i have enabled pop) 110 i got a good response saying pop is ready OK and when i tried same with telnet ipaddress 25 , it is giving connection refued.... messg..

yep just do what i write just now, and everything will going smoothly

i think you can configure your ail server remotely, you can use ssh to configure it so you don't need to back to your server and back to your windows machine. you can use putty
