|                                                                           |
| Assuming your system has POSTFIX and COURIER installed already.           |
| (installation covered in other guides such as rpm, up2date, and swup)     |
|                                                                           |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
| (1). Configure Postfix  | | | | | | | | | | | | | | | | | | | | | | | | | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

Postfix should be configured to start up on boot

   chkconfig Postfix on 

Make some configuration changes in postfix

   vi /etc/postfix/main.cf

Add / Modify the following

inet_interfaces = all
mydestination = $myhostname, localhost.$mydomain, $mydomain
myorigin = $mydomain

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
| (2). Configure Courier  | | | | | | | | | | | | | | | | | | | | | | | | | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

Configure postfix to deliver mail to a Maildir mailbox:

   vi /etc/postfix/main.cf 

home_mailbox = Maildir/

   service postfix reload 

For plain text authentication:

   vi /etc/courier-imap/pop3d 

POP3AUTH="PLAIN"

   service courier-pop3d restart 

Since pop3 is a daemon, configure it to run whenever the machine boots:

   chkconfig --level 3456 courier-pop3d on

Test your work.  Attempt to telnet localhost 110.

   Courier-pop -ERR Maildir: No such file or directory

Courier looks for the user's mail in /home/users/username/Maildir/ by
default.  If you're putting your mail somewhere else, you'll need to
edit your auth*rc file in /etc/courier/ to tell Courier about it.  The most
likely cuase of this error is the absence of the Maildir in user's home.

| (3). Configure uw-imap  | | | | | | | | | | | | | | | | | | | | | | | | | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

Configure postfix to deliver mail to a unix mailbox:

   vi /etc/postfix/main.cf 

mail_spool_directory = /var/spool/mail

   service postfix reload 

   ls -d /var/spool/mail 

drwxr-x--- 2 mail users 4096 Jan 4 14:59 /var/spool/mail/

if that directory doesn't exist, create it:

   mkdir /var/spool/mail
   chown mail:users /var/spool/mail
   chmod u+rwx /var/spool/mail
   chmod g+rx /var/spool/mail
   chmod o-rwx /var/spool/mail 

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |
| (4). Configure xinetd | | | | | | | | | | | | | | | | | | | | | | | | | | |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | |

Create the entry for xinetd:

   vi /etc/xinetd.d/pop3 

# default: on
# description:
service pop3
{
        socket_type             = stream
        wait                    = no
        user                    = root
        server                  = /usr/sbin/uw-ipop3d
        disable                 = no
}
