UPDATE: The Error's from http://mxtoolbox.com MX lookup (SMTP Went away after editing the MX record)
1. https error: "The underlying connection was closed: An unexpected error occurred on a send.
(https://mydomain.com)"
2. dns error: "mydomain.com SOA Serial Number Format is Invalid "
HTTPS: is because I have no SSL cert.
DNS: May have something to do with AWS Route 53: http://docs.aws.amazon.com/Route53/late … cords.html
And I did edit /etc/postfix/main.cf
myhostname = mail.mydomain.com
mydestination = $myhostname, localhost, localhost.localdomain, localhost.$myhostname
No fix as of yet, but
nano /var/log/mai.log
