Install Quota and Sieve Plugin for Dovecot Mailserver

To use Quota, you will first need to make sure you are using Dovecot's deliver for delivering incoming mail to users' mailboxes. Then, you need to enable the Quota plugin in your dovecot.conf

First we will start with configuring PostfixAdmin To Enable Quota Limits,

vim /var/www/postfixadmin/config.inc.php

$CONF['quota'] = 'YES';
$CONF['used_quotas'] = 'YES';
$CONF['new_quota_table'] = 'YES';

These enable the quota configuration within PostfixAdmin.

The "quota" field in the table mailbox is the user quota limit which postfixadmin enters in Megabytes and is stored in bytes.
The "maxquota" field in the domain table is the domain quota limit.
The SuperAdmin within PostfixAdmin has control over these values.

Enabling Quota Mailbox Limits in Dovecot,

Install Dovecot LDA and SASL for Postfix Mailserver

The Dovecot LDA is a local delivery agent which takes mail from an MTA and delivers it to a user's mailbox.

Key features :-

1. Mailbox indexing during mail delivery which provides faster mailbox access later.
2. Quota enforcing by a plugin.
3. Sieve language support by a plugin.

Here I will explain how to configure Dovecot as your LDA/MDA having MTA running under Postfix. And also I will cover giving Quota and sieve support to Dovecot.

The Mail server installation can be followed from the link below,
postfix-mailserver

The above documentation uses Postfix itself as LDA and this should be modified as explained below.

First we need to add the following to the master file,

vim /etc/postfix/master.cf

dovecot unix - n n - - pipe
  flags=DRhu user=dovecot:dovecot argv=/usr/local/libexec/dovecot/deliver -f ${sender} -d ${recipient}

Now we need to tell postfix to use dovecot as LDA,

Web monitoring with zabbix

A detailed explanation of zabbix server and client installation and its concepts are mentioned in the below links.

 Zabbix Installation
 Basic Concepts

Here I will explain how to monitor a website, Its downloading speed and successful logins.

For web monitoring we need to,
Create a Host from the configuration tab.
create an application for that host and name it as web_sitename or whatever.
Then go to "web" from configuration tab, From there you can create new scenario.

We need to specify,
1. application name
2. Scenario name
3. Update interval
4. Agent (any listed browser)
5. variable ( Can give username and password as variables )
      For example {user}=admin
                            {password}=zabbix

How to monitor with zabbix

The concept of zabbix is little different, its time consuming to understand its working. You can find the installation procedures of zabbix server and client from the link below.

zabbix installation                                                                                    

After the installation, log in with the admin username and password. From the administration tab we can create new user groups and users.
Next to that in Mediatype tab where we can configure smtp server, sms modems and jabber gateways for each groups and for each users.
And from  the configuration tab we can create new hosts, provide ips and link specfic templates (contains Items for common operating systems checks, such as Linux, Solaris, MAC OS X and Windows systems) and save it. Their will be many built in template from which we can choose or we can import a specific template from xml file.
Each template may contain built in applications like (CPU, Filesystems, Security etc) and under each application their will be built in items which can be considered the "data collectors". Custom scripts can also be created as items.
