9. yum -y install gcc
10. gcc poppassd.c -o poppassd -lcrypt
11. mv poppassd /usr/local/bin/
12. yum -y install xinetd
13. cp /etc/xinetd.d/time-stream /etc/xinetd.d/poppasswd
14. vim /etc/xinetd.d/poppasswd
    1. Update "service time" to "service poppasswd"
    2. disable = no
    3. id = poppasswd
    4. type = UNLISTED
    5. user = root
    6. group = root
    7. server = /usr/local/bin/poppassd
15. systemctl restart xinetd
16. systemctl enabled xinetd
17. Test by doing "telnet localhost 106" that service is started properly or not
18. cd /usr/share/squirrelmail/config
    1. ./conf.pl
    2. Plugins
    3. compatilibility
    4. change_pass
    5. S
    6. Q
19. vim change_pass/functions.php

    Near line 54 comment "//if(!preg_match('/^2\d\d/', $result)) {" and insert another line "if(!preg_match('/Cha/', $result)) {"

21. vim kill_poppassd.sh

    #!/bin/bash
    killall poppassd

22. chmod +x kill_poppassd.sh
