Hello,
Problem Statement

For one user I have added, I am able to send an email out, but when I reply to this email (i.e sending it back to the originating address), I get
Delivery to the following recipient failed permanently:

What I have tried to resolve this issue
After installing the application, I had tried changing my hostname. I did the following changes
Changed the hostname, edited the following files, With this my hostname is kept as mail.isdcgroup.com
/etc/hosts
/etc/sysconfig/network
I wrote to amazon to set my reverse dns and the reverse DNS is set correctly
[root@mail ~]# dig mail.isdcgroup.in

I have set the A record, MX record and TXT record in to my DNS (of my domain vendor )
Please see attachment1 for screenshots
The txt record setting was as per the suggestion on a google support post, I had just done the changes and I am assuming my dns update will take some time as the below out put run just now returns
[root@mail ~]# amavisd -c /etc/amavisd/amavisd.conf testkeys
TESTING#1: dkim._domainkey.isdcgroup.in => invalid (public key: not available)
Below is my “netstat –tap” output..
[root@mail ~]# netstat -tap

To test my MX record updation, I tested my SNMP connection using mxtoolbox.com. Below is the output from the tests..

However I am getting an connection lost in the SMTP transcript which I am unable to comprehend.
I am not able to hit at any point beyond this and need help in figuring out. Please extend your help with troubleshooting tips or redirect me to posts which has been previously raised for this issue (I could find only a recent one and I have done all the troubleshooting mentioned in there)
