Setup your MAIL Exchange server with zarafa on CentOS 6 Part 2

Before starting with this post you need to follow the steps which we have followed in the part1

SO Guys lets start with the phase 3 

now starting with the phase 3 lets start with the configurations of postfix. 

Add hostname entries in /etc/hosts file as shown below:

# vi /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.101   mail.rathi.com      mail

 I disabled SELinux to reduce complexity in postfix configuration.

If you want to keep SELinux on, enter the following command in Terminal:

# togglesebool httpd_can_network_connect

Allow the Apache default port 80 and port 443 if you are using ssl and 3306 if your mysql is on another server  through your firewall/router:

# vi /etc/sysconfig/iptables

[...]
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
[...]

fowling are optional as they will come in picture if you are using production or more complex setup of more than one server

[...]
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443-j ACCEPT
[...]

and same true for 3306 as well.

Configuring Postfix

Edit /etc/postfix/main.cf,

# vi /etc/postfix/main.cf

find and edit the following lines:

## Line no 75 - Uncomment and set your mail server FQDN ##
myhostname = mail.rathi.com

## Line 83 - Uncomment and Set domain name ##
mydomain = rathi.com

## Line 99 - Uncomment ##
myorigin = $mydomain

## Line 116 - Set ipv4 ##
inet_interfaces = all

## Line 119 - Change to all ##
inet_protocols = all

## Line 164 - Comment ##

#mydestination = $myhostname, localhost.$mydomain, localhost,

## Line 165 - Uncomment ##\
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain

## Line 419 - Uncomment ##
home_mailbox = Maildir/

Save and exit the file. Start/restart Postfix service now:

# service postfix restart
# chkconfig postfix on

Testing Postfix mail server

First, create a test user called “nrathi“.

# useradd nrahi
# passwd nrathi

Access the server via Telnet and enter the commands manually shown in red colored text.

# telnet localhost smtp

Trying ::1...
Connected to localhost.
Escape character is '^]'.
220 mail.rathi.com ESMTP Postfix
ehlo localhost     ## type this command ##
250-mail.rathi.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-ENHANCEDSTATUSCODES
250-8BITMIME
250 DSN
mail from:<nrathi>     ## Type this - mail sender address##
250 2.1.0 Ok
rcpt to:<nrathi>     ## Type this - mail receiver address ##
250 2.1.5 Ok

354 End data with <CR><LF>.<CR><LF>
welcome to rathi.com mail server     ## Enter the boddy of the email ##.
     ## type dot (.) to complete message ##
250 2.0.0 Ok: queued as B822221522
quit     ## type this to quit from mail ##
221 2.0.0 Bye
Connection closed by foreign host.

Now navigate to the user “nrathi“ mail directory and check for the new mail:

ls /home/nrathi/Maildir/new/

Sample output:

1390215275.Vfd00Ie04f8M357080.mail.rathi.com

A new mail is received to the user “nrathi“. To read the mail, enter the following command:

# cat /home/nrathi/Maildir/new/1390215275.Vfd00Ie04f8M357080.mail.rathi.com

Sample output:

Return-Path: <nrathi@rathi.com>
X-Original-To: nrathi
Delivered-To: nrathi@rathi.coml
Received: from localhost (localhost [IPv6:::1])
    by mail.rathi.com (Postfix) with ESMTP id B822221522

Add the following line at the end.

mailbox_command = /usr/bin/zarafa-dagent “$USER”

Save and close the file. Restart postfix service to take effect the saved changes.

# service postfix restart

The remaining things i will cover in the next part phase 4
