'''<nowiki>Pre-Installation steps on first MTA+Mailbox server [10.5.14.15]:</nowiki>'''


# Install CentOS 6.2 x86_64 on server.
# Disable SELinux in file “''/etc/sysconfig/selinux''” :

''<nowiki># vim /etc/sysconfig/selinux</nowiki>''

SELINUX=disabled


# Disable the Firewall:

''<nowiki># system-config-firewall</nowiki>''


# Disable iptables and sendmail services:

''<nowiki># /etc/init.d/postfix stop</nowiki>''

''<nowiki># chkconfig postfix off</nowiki>''

''<nowiki># chkconfig iptables off</nowiki>''

''<nowiki># chkconfig ip6tables off</nowiki>''


# Disable MySQL if installed and running:

''<nowiki># /etc/init.d/mysqld stop</nowiki>''

''<nowiki># chkconfig mysqld off</nowiki>''


# Yum repository must be configured to install packages and other dependencies:

''<nowiki># wget </nowiki>[http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm]

Install DAG's GPG key:

''<nowiki># rpm --import </nowiki>[http://apt.sw.be/RPM-GPG-KEY.dag.txt http://apt.sw.be/RPM-GPG-KEY.dag.txt]

Install the repository package:

''<nowiki># rpm –ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm</nowiki>''

This will add a yum repository config file and import the appropriate GPG keys.


# Install and configure NTP to synchronize the system clock:

''<nowiki># yum install ntp</nowiki>''

''<nowiki># chkconfig ntpd on</nowiki>''

''<nowiki># ntpdate -u pool.ntp.org</nowiki>''

''<nowiki># /etc/init.d/ntpd start</nowiki>''


# Now start installation of Centos 6.2 packages required by ZCS 7.2

''<nowiki># yum install nc perl sudo sysstat gmp libidn libstdc++ sqlite libtool-ltdl bind bind-chroot bind-libs bind-utils -y </nowiki>''


# Configure hostname of the server and DNS for the domain:

Make sure that in '''''/etc/hosts'', the hostname of the server has been pointed to the IP address of the server.'''

# Create download directory for zimbra package:

''<nowiki># mkdir /download</nowiki>''

''<nowiki># cd /download</nowiki>''


# Download ZCS – Network Edition from [http://www.zimbra.com/products/download_network.html http://www.zimbra.com/products/download_network.html]

Select architecture (x86 or x64) according to the installed Operation System and fill registration form.


# Now extract the download zimbra tarball and start installation:

''<nowiki># tar –xvzf </nowiki>''zcs-NETWORK-7.2.0_GA_2669.RHEL6_64.20120410002117.tgz

''<nowiki>#./install.sh --platform-override –license /root/Desktop/ZCSLicense.xml</nowiki>''


Note: If we install Zimbra Collaboration Suite on Centos, we have to add ‘--platform-override’ when run the ‘install.sh’ script. Otherwise the installation will stop because the system is not detected as RedHat OS.


The output should look something like:

First, we need to agree with the license terms.


<nowiki>Do you agree with the terms of the software license agreement? [N] </nowiki>'''y'''


Now, Zimbra will check all the prerequisites. If anything is not found, stop the Wizard and install it with yum.

If everything is ok, the script will ask what the packages that we want to install are. Just select the default options.

Afterwards, the script asks you if you want to override the platform. You say "yes", of course.


You appear to be installing packages on a platform different

than the platform for which they were built.


This platform is CentOS6_64

Packages found: RHEL6_64

This may or may not work.


Using packages for a platform in which they were not designed for

may result in an installation that is NOT usable. Your support

options may be limited if you choose to continue.


<nowiki>Install anyway? [N] </nowiki>'''y'''

<nowiki>The system will be modified. Continue? [N] </nowiki>'''y'''


During installation, setup shows error like this then enter the domain name:

<nowiki>Change domain name? [Yes]</nowiki>

# Create download directory for zimbra package:

# Download ZCS – Network Edition from [http://www.zimbra.com/products/download_network.html http://www.zimbra.com/products/download_network.html]

Select architecture (x86 or x64) according to the installed Operation System and fill registration form.


# Now extract the download zimbra tarball and start installation:

Note: If we install Zimbra Collaboration Suite on Centos, we have to add ‘--platform-override’ when run the ‘install.sh’ script. Otherwise the installation will stop because the system is not detected as RedHat OS.


The output should look something like:

Now, Zimbra will check all the prerequisites. If anything is not found, stop the Wizard and install it with yum.

If everything is ok, the script will ask what the packages that we want to install are. Just select the default options.

Afterwards, the script asks you if you want to override the platform. You say "yes", of course.


You appear to be installing packages on a platform different

than the platform for which they were built.


This platform is CentOS6_64

Packages found: RHEL6_64

This may or may not work.


Using packages for a platform in which they were not designed for

may result in an installation that is NOT usable. Your support

options may be limited if you choose to continue.

'''Restrict Users to send e-mail only in Local Domain:'''


# This type of customization is performed on postfix level.

On mailserver.bbfgroup.com login as as root user and then switch to zimbra user: 

''<nowiki># su - zimbra</nowiki>''


# Edit ''/opt/zimbra/conf/postfix_recipient_restrictions.cf ''and add following restriction rule on top of the file:

check_sender_access hash:/opt/zimbra/postfix/conf/bbfgroup_restricted_users


# Edit ''/opt/zimbra/conf/zmmta.cf'' and add following line at the end of '''"SECTION mta DEPENDS amavis"''' 

just before '''"RESTART mta"''':

POSTCONF smtpd_restriction_classes local_bbfgroup_only

POSTCONF local_bbfgroup_only FILE postfix_check_recipient_access.cf


# Create a new file /''opt/zimbra/conf/postfix_check_recipient_access.cf ''and add following line:

check_recipient_access hash:/opt/zimbra/postfix/conf/local_bbfgroup_domains, reject 


# Create a new file ''/opt/zimbra/postfix/conf/bbfgroup_restricted_users'' and add user with the pre-defined format:

apcups1@bbfgroup.comlocal_bbfgroup_only

apcups2@bbfgroup.comlocal_bbfgroup_only


# Create a new file ''/opt/zimbra/postfix/conf/local_bbfgroup_domains'' and list all the domains where 

'''''bbfgroup_restricted_users '''''allowed to sent mails. Please follow this syntax : 

bbfgroup.comOK


# Update new posfix configuration files using these commands and restart zimbra MTA: 

''$ postmap /opt/zimbra/postfix/conf/bbfgroup_restricted_users''

''$ postmap /opt/zimbra/postfix/conf/local_bbfgroup_domains''

''$ zmmtactl stop''

''$ zmmtactl start''


After applying these setting, all of restricted user will have limited access for sending an email and they will allowed only to sending an e-mail to bbfgroup domain only as listed on file ''/opt/zimbra/postfix/conf/local_bbfgroup_domains''


Note :

1. These setting will must be re-written after upgrading Zimbra

2. To restore restricted user access so they could sending for various domain, please : Remove any added configuration on zmmta.cf and make sure that the restriction setting will applied to blank account. Run this command : postconf -e smtpd_restriction_classes and zmmtactl reload to restore the setting.
