No, it does not solve my problem.
I want to configure postfix to send and receive mails locally (to every system of local area network). I tried this.
http://www.postfix.org/STANDARD_CONF...ON_README.html (postfix on a local network.)
I do not have domain that's why I do not want to receive mails from out side local network.
I can send it on every domain of the world but I am not able to send and receive it locally because of no domain.
I can send it to other users of same server where postfix is installed but I am not able to send to other systems of LAN.

Please help.

Thank you very much.

As far as I'm aware if you don't have a domain in the mydomain directive in main.cf your mail will just be dropped. however you can set a garbage domain like:
mydomain = wotnot.test

Your LAN will need to know the MX record of the garbage domain so the dns server your LAN is pointing to will need to know this (or you'll need to put it in the hosts file eg: 1.1.1.2 wotnot.test)

Bear in mind if you're sending to a proper bonafide mail server on the internet your mail will likely be treated as spam and binned straight away. if you're sending to another postfix box on your own lan you should be ok.

Sorry if you know all this already.

You want to configure a mail-server for your Local Area Network. You do not have domain name.
It is a very basic requirement and it can be done easily. As you have already selected postfix, so no need to tell you about installation of mail server.

You have asked in your first post that you want to see local mails in mail client.
Install Squirrelmail for this.
If you have configured your system correctly, you can send mails to other IP's of same network as well as receive too.
All you can do using mail client Squirrelmail

What you have to do.
1) Setup DNS server and add the Mail server MX records in the forward and reverse zone files.
2) You need to add hostname entries in /etc/hosts file.
3) Configure your main.cf
Code:
myhostname = server.test.local
mydomain = test.local
myorigin = $mydomain
inet_interfaces = all
inet_protocols = all
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mynetworks = 192.168.1.0/24, 127.0.0.0/8
home_mailbox = Maildir/
Restart Postfix.
4) Now install Dovecot
Dovecot is an open source IMAP and POP3 mail server for Unix/Linux systems.
Configure it correctly.
5) Now install and configure Squirrelmail.

Here is complete mail system for your local area network.
