Restart the IMAP SSL Daemon

Stopping Courier IMAP-SSL server: imapd-ssl.
Starting Courier IMAP-SSL server: imapd-ssl.

We are not going to be using the IMAP Daemon , let 's disable it from starting when the system starts. 
# ls -l /etc/rc2.d/S* |grep imap
lrwxrwxrwx 1 root root 22 2011-08-04 15:07 /etc/rc2.d/S20courier-imap -> ../init.d/courier-imap
lrwxrwxrwx 1 root root 26 2011-08-04 16:41 /etc/rc2.d/S20courier-imap-ssl -> ../init.d/courier-imap-ssl
# update-rc.d -f courier-imap remove 
 Removing any system startup links for /etc/init.d/courier-imap ...

   /etc/rc4.d/S20courier-imap
   /etc/rc5.d/S20courier-imap

Cool, now the IMAP SSL DAEMON is listening on port 993 and your email client should connect fine when set to use:
SSL/TLS for the communication encryption
and Normal password for the Authentication Method.
