CentOS 6.4 Email Gateway (Part 7)

Now we'll install MailWatch with the web GUI for MailScanner. Let's begin. Open Putty and enter:

yum install php-gd php-mysql -y

Edit the /etc/php.ini file and ensure each variable below is set with these values:

short_open_tag = On
safe_mode = Off
register_globals = Off
magic_quotes_gpc = On
magic_quotes_runtime = Off
session.auto_start = 0

Save and close the php.ini file.

Change to the temp directory:

cd /tmp

Download the latest stable version of MailWatch:

wget http://sourceforge.net/projects/mailwatch/files/mailwatch/

Extracted the package we just downloaded:

tar xzvf mailwatch-

Change directory to access the newly extracted files:

cd mailwatch-

Now we'll create the database:

mysql -u root -p < create.sql

Login to mysql as a root:

mysql -u root -p

We'll now create a MySQL user and then set password and configure MailScanner for SQL logging. In this example we're creating a user called mailwatch with a password of letmein. (Change the username and password to suit your needs):

GRANT ALL ON mailscanner.* TO mailwatch@localhost IDENTIFIED BY 'letmein';
GRANT FILE ON *.* TO mailwatch@localhost IDENTIFIED BY 'letmein';
show databases;

Now we'll edit the MailWatch.pm file and change the database values to suit the values we just created above. The file is located here /tmp/mailwatch- The variables we need to change are:

my($db_name) = 'mailscanner';
my($db_host) = 'localhost';
my($db_user) = 'mailwatch';
my($db_pass) = 'letmein';

Now we need to move MailWatch.pm to /usr/lib/MailScanner/MailScanner/CustomFunctions like so:

cd MailScanner_perl_scripts
cp MailWatch.pm /usr/lib/MailScanner/MailScanner/CustomFunctions

Now we'll create the MailWatch web user. This is the user you will log onto the web GUI with:

mysql mailscanner -u mailwatch -p

Once logged on run the query below:

INSERT INTO users SET username = 'admin', password = md5('letmein'), fullname = 'MAilwatch Administrator', type ='A';

Using the query above, you would have created a user called admin and the password is letmein. Change these values to suit your needs.

We're now ready to install MailWatch. Change back to the MailWatch Folder:

cd ..

Move mailscanner folder for web root folder:

mv mailscanner /var/www/html/

Change directory to the mailscanner folder in web root directory:

cd /var/www/html/mailscanner

Set the folder permissions as outlined below:

chown root:apache images
chmod ug+rwx images
chown root:apache images/cache
chmod ug+rwx images/cache

We'll now create a conf.php file by copying conf.php.example file:

cp conf.php.example conf.php

Now edit the following database values to suit the values you created earlier. In my case the user was mailwatch and password was letmein.

define('DB_TYPE', 'mysql');
define('DB_USER', 'mailwatch');
define('DB_PASS', 'letmein');
define('DB_HOST', 'localhost');
define('DB_NAME', 'mailscanner');

Now we need to stop the MailScanner service:

service MailScanner stop

Now we'll edit the /etc/MailScanner/MailScanner.conf file:

Ensure that the variables below are set as shown:

Always Looked Up Last = &MailWatchLogging
Detailed Spam Report = yes
Quarantine Whole Message = yes
Quarantine Whole Messages As Queue Files = no
Include Scores In SpamAssassin Report = yes
Quarantine User = root
Quarantine Group = apache (this should be the same group as your web server)
Quarantine Permissions = 0660

Save and close the /etc/MailScanner/MailScanner.conf file.

Edit the file /etc/httpd/conf/httpd.conf. Go to the end of the file and add:

#Start of add

<VirtualHost *:80>

# Admin email, Server Name (domain name) and any aliases
ServerAdmin support@Matrix7.com.au

# Index file and Document Root (where the public files are located)
DirectoryIndex index.php index.html
DocumentRoot //var/www/html/mailscanner


#End of Add

Make sure you change the ServerAdmin email address to your email address and also the IP addresses above ( to your servers IP Address. Save and close the file.

Now we'll restart the MailScanner service:

service MailScanner start

We'll also restart the web server Apache:

service httpd restart

Now open up your browser and type in the IP address of your server like:

You should now see the MailWatch log on screen:


Type in your username and password that you set earlier in this tutorial. Mine in this example was admin and password was letmein.

One final thing, I highly advise you to install and configure BIND DNS on your system for optimal results and spam protection. You can see a quick tutorial on this subject by clicking here...

All done! Consider yourself a superstar!!! 🙂
