Web and Mail System
This is a frontend system it provides the mail and web interfaces, mail is delivered to the server and at the same time it serves as the web interface for both administration as well as end user access. This system requires a backend system or distributed backend systems. You can have several of these nodes scaling up or down as demand grows or drops.
This profile is used in the Distributed Backend Hybrid Frontend and Single Backend Hybrid Frontend topologies.
Automated Configuration
Baruwa Enterprise Edition >= 2.0.7 uses an automated wizard based utility called
baruwa-setup to configure, update and manage the system. This utility collects
configuration information from the user, performs any required software updates
and then configures the system based on the profile selected and the configuration
data collected. This simplifies the whole setup and management process so the
user does not have to edit any configuration files.
A pass phrase is required to secure the authentication information that is collected.
Make sure you choose a strong pass phrase which is easy for you to remember but difficult to guess for others, a long sentence describing a personal experience is a good pass phrase.
To start the configuration process login to the server with the username root and
the password you set during installation.
Then issue the baruwa-setup command at the command prompt:
baruwa-setup
The program will ask you to set a passphrase, enter the passphrase and press enter re-enter the same passphrase again to confirm. If the passphrase is accepted the System settings screen below will be displayed.
Warning
Do not loose this passphrase, there is no way to recover it. A reinstallation will be required if you loose the passphrase.

SSL/TLS Settings
The Baruwa web interface MUST ran over SSL/TLS, other services such as SMTP AUTH
only work over SSL/TLS as well. So you need to either purchase a valid SSL certificate
or have baruwa-setup automatically generate one non recognised SSL certificate for
you. If you do not have a CA issued certificate and do not intend on purchasing one
the leave the I have a CA issued Certificate unchecked.
The certificate that baruwa-setup generates will cover the web hostname, web aliases,
cluster members and the mail hostname. This means that you should copy this certificate to
other cluster hosts that you specified and select I have a CA issued Certificate on
those hosts when you set them up instead of generating new certificates for them.
Note
We have partnered with the SSLShop to bring you discounted
SSL certificate pricing. RapidSSL CA signed certificates can
be purchased at discounted pricing using the Discount coupon
“BARUWA” from http://www.sslshop.co.za
If you have a SSL certificate that is issued by a recognised CA and would
like Baruwa to use it, install it prior to running baruwa-setup. Please NOTE
that you need certificates that cover the web hostname and aliases, and the mail
hostname. Please check I have a CA issued Certificate.
The preferred location to install certificates and keys on the server is under /etc/pki.
You need to create a directory structure under that and store your certificate under it.
The following example creates a baruwa directory under /etc/pki and stores the
certificates and keys there:
mkdir -p /etc/pki/baruwa/{certs,private}
Create the following files
/etc/pki/baruwa/certs/baruwa.pemwith the contents of your SSL certificate/etc/pki/baruwa/private/baruwa.keywith the contents of your SSL private key
You need to create additional certificate pairs if your web hostname and mail hostname are not the same.
If you have a wildcard certificate with all your names being subdomains of that domain to which the certificate is issued then you can simply create one pair.
If you left I have a CA issued Certificate unchecked you will be presented with
the following screen. You need to fill in the details which are used to create a
CA from which the certificate will be issued. The description of the options is as
follows:
| Option | Description |
|---|---|
| Organization | OpenSSL CA Name
|
| Email Address | OpenSSL email address
|
| Country | OpenSSL country code
|
| Province | OpenSSL province
|
| City | OpenSSL city
|
If you checked I have a CA issued Certificate you will be presented with the following
screen, you need to specify the locations of your certificates and keys. The description of
the options is as follows:
| Option | Description |
|---|---|
| Web Certificate | The location of the web certificate file in PEM format |
| Web Private Key | The location of the web private key file in PEM format |
| Mail Certificate | The location of the mail certificate file in PEM format |
| Mail Private Key | The location of the mail private key file in PEM format |
Setup Running
At this point there is nothing left for you to do until the setup is complete.
The program will update the screen with status information as well as logging
it to /var/log/messages. If an error occurs the error information will be
displayed until you press the enter button and the program will exit.
Warning
If an error occurs while running setup, DO NOT REINSTALL the system copy
the error and contact support.
Setup Complete
When the setup is complete the following screen will be displayed simply press enter and the program will exit
To ensure that all the settings are correctly applied reboot the server
from the command line using the command:
reboot
Post Configuration
Now that the installation and setup are complete, you need to finalize the setup by Adding a Scanning Node, Adding an Organization, Adding a Domain and Adding an Account. This is done through the management web interface.
The exact sequence to follow is:
- Add the Node
- Add an Organization
- Add a Domain Administrator for the organization
- Edit the Organization and assign Domain Administrator to the organization
- Add a Domain to the Organization
- Add a delivery server for the Domain
- Add any user accounts to the Domain if not using external authentication
Review the DNS, Administrators guide, Email Protection Best Practices and Advanced configuration sections for other configuration and setup options available.
