Usage instructions
For extensive instructions see: http://floatingcloud.io/mail-server-linux-postfix-using-mysql-tons-users/
Before logging into to your server via ssh, you need to make sure that you first set up an elastic IP address and DNS records. You need to setup the DNS with both an A record and an MX record.
You need to first attach an Elastic IP to your instance, this way the IP address will not change when the server is turned off and on. Follow these instuctions: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html
You then need your DNS to have an A record to point to the IP address of the server. The A record is the domain or sub-domain that you plan to use for this server.
You then need to make an MX record point to that A record. This makes the Instance open to receive email from the rest of the Universe.
To login go to your AWS EC2 panel, click on your new instance and follow the login instructions to SSH login. become root sudo -i cd /opt/postfix-containerized/docker-files BE SURE TO use the correct fqdn and that it ALready has MX record . run the command ./prepare-postifx.sh YOUR-FULLY-QUALIFIED-DOMAIN-NAME
This script creates an https certificates which are used by the mail server and the webmail as well as an admin user with username admin@YOUR-FQDN . Open https://YOUR-FQDN the password is the Instance ID To add users login to https://YOUR-FQDN/admin with same credentials, click on "Add Mailbox"
