Hi all,
First of all i would like to share my regards to everyone in this community.This is my first post in the forum.

I have two machines one is opensuse machine running local dns server as well as mail server(postfix) and other machine centos acting as a client.
I have named the suse machine as ‘suse1′(192.168.1.100) and centos machine as ‘centos'(192.168.1.200) and both are in a local domain named ‘dns.internal’.I have updated the host records in the dns configuration files.I am able to ping as well as to ssh into both of the machines.I am able to resolve both of the machine names.Now coming to my problem.The user [email protected] is able to receive mails from [email protected] but the reversse is not happening that is the user [email protected] is not able to receive mails from [email protected]

Mail Logs are as follows
