postfix not working over LAN

i am trying to Configure a mail transfer agent (MTA) to accept inbound email from other systems and
Configure an MTA to forward (relay) email through a smart host.

Code:

#postconf -e inet_interface=all

#postconf -e myorigin=server.example.com 

#postconf -e mynetworks="127.0.0.0/8 192.168.137.0/24"

#service postfix restart

here "server.example.com is my machine name"(192.168.137.1}

i am able to send mail to the users of my machine via

Code:

#mail user1

hiii

EOT

but when i try to send mail to the users of other machine over my lan 192.168.137.2

Code:

#mail user2@192.168.137.2

hiii

EOT

the mail is not able to reached to any user of 192.168.137.2.

Logs are your friends try something like this

Code:

less /var/log/maillog

Code:

less /var/log/mail.log

Depending on your system. This can tell you whats happening behind the scenes.

JC

please configure the postfix to process all lan queries

Following jrosco's comments, please try 'tailf /var/log/maillog' in one terminal then attempt to send an email in another terminal. If you post the logs from that time period we can assist with troubleshooting.

Where is this mailbox located?

Please try 'mail shank@[192.168.137.1]' and see what the logs say

when i use 'mail shank@[192.168.137.1]' it says in /var/log/maillog that connect to 192.168.137.1[192.168.137.1]:25:connection refused status : deffered

Sounds like it's not accepting connections .. try running 'netstat -tnlp | grep postfix' on 192.168.137.1.
