Note: use your own details

#chown -R vpopmail:vchkpw /var/qmail/control/clientcert.pem /var/qmail/control/servercert.pem

#cd /usr/src/qmail/ucspi-tcp-0.88/
#patch < /downloads/qmailrocks/patches/ucspi-tcp-0.88.errno.patch
#make && make setup check
#cd /package/admin/daemontools-0.76
#cd /package/admin/daemontools-0.76/src
#patch < /downloads/qmailrocks/patches/daemontools-0.76.errno.patch
#cd /package/admin/daemontools-0.76
#package/install

Step2: EZmlm (Mailing list manager )

#cd /downloads/qmailrocks/
#tar zxvf ezmlm-0.53-idx-0.41.tar.gz
#cd ezmlm-0.53-idx-0.41
#make && make setup

Step3: AutoResponder

#cd /downloads/qmailrocks
#tar zxvf autorespond-2.0.5.tar.gz
#cd autorespond-2.0.5
#make && make install

Step 4 – Vpopmail  (without MySQL integration)

#cd /downloads/qmailrocks
#tar zxvf vpopmail-5.4.13.tar.gz
#cd vpopmail-5.4.13
#./configure –enable-logging=p
#make && make install-strip

Step 5 – Vqadmin ( Virtual Domain Creation by Web panel)

#cd /downloads/qmailrocks
#tar zxvf vqadmin-2.3.6.tar.gz
#cd vqadmin-2.3.6
#./configure –enable-cgibindir=/var/www/cgi-bin –enable-htmldir=/var/www/html
#make && make install-strip

Password protection for vqadmin panel >

#vi /etc/httpd/conf/httpd.conf

<Directory “/var/www/cgi-bin/vqadmin”>
deny from all
Options ExecCGI
AllowOverride AuthConfig
Order deny,allow
</Directory>

#cd /var/www/cgi-bin/vqadmin
#vi .htaccess

AuthType Basic
AuthUserFile /var/www/cgi-bin/vqadmin/.htpasswd
AuthName vQadmin
require valid-user
satisfy any
#chown apache .htaccess
#chmod 644 .htaccess

#htpasswd -bc /var/www/cgi-bin/vqadmin/.htpasswd admin india123

where:
username: admin
password:india123

#chmod 644 .htpasswd
#service httpd restart

NOW OPEN YOUR BROWSER AND CREATE A  DOMAIN

http://192.168.1.254/cgi-bin/vqadmin/vqadmin.cgi

#make && make install-strip

NOW OPEN YOUR BROWSER TO OPEN QMAIL ADMIN
http://192.168.1.254/cgi-bin/qmailadmin

after login >>

Step 8 – Finalizing Qmail

# sh /downloads/qmailrocks/scripts/finalize/linux/finalize_linux.script

#vi /var/qmail/supervise/qmail-pop3d/run

Find “mail.example.com” and change it to your server’s hostname. For example: mail.mydomain.com.

#vi /var/qmail/supervise/qmail-smtpd/run

Find “mail.example.com” and change it to your server’s hostname. For example: mail.mydomain.com

#qmailctl stop
#echo ‘127.:allow,RELAYCLIENT=””‘ >> /etc/tcp.smtp
#qmailctl cdb

#echo postmaster@ > /var/qmail/alias/.qmail-root
#echo postmaster@ > /var/qmail/alias/.qmail-postmaster
#echo postmaster@ > /var/qmail/alias/.qmail-mailer-daemon

#ln -s /var/qmail/alias/.qmail-root /var/qmail/alias/.qmail-anonymous
#chmod 644 /var/qmail/alias/.qmail*

Step 9: Uninstall Sendmail/Postfix

#/etc/rc.d/init.d/sendmail stop
#rpm -e –nodeps sendmail-x.x.x.x
#rpm -e –nodeps sendmail-doc-x.x.x.x
#rpm -e –nodeps sendmail-devel-x.x.x.x
#rpm -e –nodeps sendmail-cf-x.x.x.x
#/etc/rc.d/init.d/sendmail stop
#mv /usr/lib/sendmail /usr/lib/sendmail.old
#mv /usr/sbin/sendmail /usr/sbin/sendmail.old
#chmod 0 /usr/lib/sendmail.old /usr/sbin/sendmail.old
#rpm -qa | grep postfix
#/etc/rc.d/init.d/postfix stop
#rpm -e nodeps postfix-x.x-x
#ln -s /var/qmail/bin/sendmail /usr/lib/sendmail
#ln -s /var/qmail/bin/sendmail /usr/sbin/sendmail

Step 10 :  Start Qmail Service

#qmailctl stop
#qmailctl start
#qmailctl stat

#telnet 192.168.1.254 110   <—-check pop3 service
Trying 192.168.1.254…

Configure Courier IMAP & IMAP SSL

#cd /downloads/qmailrocks/
#tar jxvf courier-authlib-0.55.tar.bz2
#cd courier-authlib-0.55

# ./configure –prefix=/usr/local –exec-prefix=/usr/local –with-authvchkpw –without-authldap –without-authmysql –disable-root-check –with-ssl –with-authchangepwdir=/usr/local/libexec/authlib –with-redhat

#make && make check
#make install-strip && make install-configure
#vi /etc/rc.local
#/usr/local/sbin/authdaemond start
#useradd bsmith
#cd /downloads/qmailrocks/
#tar jxvf courier-imap-4.0.2.tar.bz2
#chown -R bsmith:wheel courier-imap-4.0.2
#cd /downloads/qmailrocks/courier-imap-4.0.2
#su bsmith
#./configure –prefix=/usr/local –exec-prefix=/usr/local –with-authvchkpw –without-authldap –without-authmysql –disable-root-check –with-ssl –with-authchangepwdir=/usr/local/libexec/authlib –with-redhat

#make && make check
#make install-strip && make install-configure
———————————————————————–

#/usr/local/sbin/mkimapdcert
#vi /usr/local/etc/imapd.cnf
change postmaser@example.com an administrative email address
Save and exit
#vi /usr/local/etc/imapd
Make sure that the following configuration exists: IMAPDSTART=YES
#vi /usr/local/etc/imapd-ssl
Make sure that the following configuration exists: IMAPDSSLSTART=YES
Make sure that the following configuration exists: TLS_CERTFILE=/usr/local/share/imapd.pem
Save and exit the file.
#vi /usr/local/etc/authlib/authdaemonrc
Around like 27, you should see the “authmodulelist” setting. Make sure that “authvchkpw” is the only module listed. Like so:
authmodulelist=”authvchkpw”
Save and exit the file.
Now we create the startup scripts…

#cp /usr/local/libexec/imapd.rc /etc/rc.d/init.d/imap
#cp /usr/local/libexec/imapd-ssl.rc /etc/rc.d/init.d/imaps

Now let’s start up Authdaemond, IMAP and IMAPS. To be safe we’ll stop each service before starting it…
#/usr/local/sbin/authdaemond stop
#/usr/local/sbin/authdaemond start
#/etc/rc.d/init.d/imap stop
#/etc/rc.d/init.d/imaps stop
#/etc/rc.d/init.d/imap start
#/etc/rc.d/init.d/imaps start

If you run “nmap localhost”, you should see both 143 and 993 now open and listening.
Now let’s test it…

#nmap localhost

#telnet localhost 143

Installing Squirrelmail

#mkdir /var/sqattachements
#chown -R apache:apache /var/sqattachements
#cd /var/www/html/webmail
#chown -R apache:apache data
#cd config
#perl ./conf.pl
