setting up mail server on Redhat Enterprise Linux 4ES
 

Hello,

i need directions on how to get a mail server running on Redhat Enterprise Linux 4ES.

i want to be able to use POP as well.

thank you.

Try here: http://www.google.com.

After you've decided on what mail server package to use, and you've got it installed, feel free to come back with specific questions if you're having problems.

RHEL will come with Sendmail by default. I'd recommend installing and using Postfix. Once Postfix is installed, do the following:

/sbin/service sendmail stop
/usr/sbin/alternatives --set mta /usr/sbin/sendmail.postfix
/sbin/service postfix start

Then go read the docs on Postfix at http://www.postfix.org

POP and IMAP are usually default on RHEL, you just need to enable their services.

Postfix is a free open source mail transfer agent (MTA), a computer program for the routing and delivery of email. It is intended as a fast, easy-to-administer, and secure alternative to the widely-used Sendmail MTA.

Postfix is the default MTA for a number of Unix(-like) operating systems such as Ubuntu[1]

Sendmail is a mail transfer agent (MTA) that supports many kinds of mail transfer and delivery including the overwhelmingly popular SMTP.


Configuring Postfix for RHLE 5.

One of the best ways to learn how to configure Postfix is to read the comments within:
/etc/postfix/main.cf.

Additional resources including information about LDAP and SpamAssassin integration are available online at

hxxp://www.postfix.org/.3.3.

Thanks guys for your responses so far.

i may have had it set up but

How do we get to know the settings for use with our mail client like evolution or outlook?

If you don't know the answers to these questions already you probably don't have the server setup correctly/completely and you may have the server setup as an open relay:

Name: Your name
Address: Your email address
SMTP Server: IP Address or Hostname of server running SMTP
POP3 Server: IP Address or Hostname of server running POP3
Account: Username on POP3 Server
Password: Password for Username on POP3 Server

You really should have auth/tls/ssl enabled or some similar mechanism which would change the setup slightly on client side.

Hope it helps!
