Postfix MTA, MDA dovecot and Roundcube mail has been configured on EC2. I am able to receive emails from internet mailboxes. Also, I am able to send email to outside emails like gmail, rediff. Only issue we are facing is I m not able to receive email from gmail or rediff.
Only people with experience in MTA/Postfix/Roundcube will be allowed to work.
The steps to be done only via team viewer
This is a error I received after a day when i send email from gmail to my MTA.
