The entire process installs the binaries and configuration files. Binary named “authdaemond” under “/usr/local/sbin” directory is executing as the authlib daemon. This consults the /usr/local/etc/authlib/authdaemonrc configuration file.

Starting the authlib daemon            
  [root@server1 ~]# /usr/local/sbin/authdaemond start
Starting authdaemond at startup     
# ln -s /usr/local/sbin/authdaemond /etc/init.d/
# ln -s /etc/init.d/authdaemond   /etc/rc.d/rc3.d/S24authdaemond

Installing courier imap (Installs the IMAP and POP3 service)
yum install openssl openssl-devel
\\\\\   As   Non Root user
                Download Courier IMAP                   
wget http://cznic.dl.sourceforge.net/project/courier/imap/4.15/courier-imap-4.15.tar.bz2

tar -xjvf courier-imap-4.15.tar.bz2
cd  courier-imap-4.15
./configure
make
# make install
# make install-configure

[root@server1 authlib]# pwd
/usr/local/etc/authlib
[root@server1 authlib]# ls
authdaemonrc  authdaemonrc.dist
The authdaemon consults authdaemonrc file ,we can change values like number of daemons and other performance related values
Starting authdaemond
# /usr/local/libexec/courier-authlib/authdaemond start


[root@server1 libexec]# pwd
/usr/lib/courier-imap/libexec
 [root@server1 libexec]# ./pop3d.rc start

allow necessary ports and disable selinux ,also check mynetworks,inet_interfaces= in main.cf

POP-SSL

Change the file /usr/lib/courier-imap/etc/pop3d.cnf  contents like email, CN etc for certificate
 Run the script:-
#./usr/lib/courier-imap/share/mkpop3dcert
cert file will be in same dir of script
#ls -l /usr/lib/courier-imap/share/
 total 24
drwxr-xr-x. 4 root root 4096 Jun 22 00:25 man
-rwxr-xr-x. 1 root root 1292 Jun 24 22:56 mkdhparams
-rwxr-xr-x. 1 root root 2319 Jun 24 22:56 mkimapdcert
-rwxr-xr-x. 1 root root 2179 Jun 24 22:56 mkpop3dcert
-rw-------. 1 root root 5463 Jun 24 23:00 pop3d.pem

To run pop-ssl we have to run the script /usr/lib/courier-imap/libexec/pop3d-ssl.rc
=>

# ./pop3d-ssl.rc start

TO enable pop3 and pop3ssl at runlevel/ startup we have to create sym-links to /etc/init.d/  and rc.d/

 for   pop

 [root@server1 ~]# ln -s /usr/lib/courier-imap/libexec/pop3d.rc /etc/init.d/

for pop-SSL

[root@server1 ~]# ln -s /usr/lib/courier-imap/libexec/pop3d-ssl.rc  /etc/init.d/

#ls -l /etc/init.d/

 ..

lrwxrwxrwx. 1 root root    38 Jun 24 23:18 pop3d.rc -> /usr/lib/courier-imap/libexec/pop3d.rc 

lrwxrwxrwx. 1 root root    42 Jun 24 23:20 pop3d-ssl.rc -> /usr/lib/courier-imap/libexec/pop3d-ssl.rc

..

...

above will only create shortcut now creating symlink to symlink @ runlevel directory thats /etc/rc.d/

[root@server1 ~]# ls /etc/rc.d/
init.d/     rc0.d/      rc2.d/      rc4.d/      rc6.d/      rc.sysinit 

rc          rc1.d/      rc3.d/      rc5.d/      rc.local 

Running in runlevel 3 :

ln -s /etc/init.d/pop3d-ssl.rc /etc/rc.d/rc3.d/S20pop3dssl

the name should be unique "S20pop3dssl"   , note=>S=start 

Starting pop and pop-ssl

[root@server1 rc3.d]# ./S21pop3d start

[root@server1 rc3.d]# ./S20pop3dssl start

 Check if port is listening by netstat -antpl

Setting up imap and imap ssl to run at runlevel 3 at start up
ln -s /usr/lib/courier-imap/libexec/imapd.rc /etc/init.d/

ln -s /etc/init.d/imapd.rc /etc/rc.d/rc3.d/S22imapd

ln -s /usr/lib/courier-imap/libexec/imapd-ssl.rc /etc/init.d/ln -s /etc/init.d/imapd-ssl.rc /etc/rc.d/rc3.d/S23imapssld
