#postfix send only mail setup:

https://www.digitalocean.com/community/tutorials/how-to-install-and-configure-postfix-as-a-send-only-smtp-server-on-ubuntu-14-04

Steps:

1. apt-get install mailutils

2. Select "internet site" for mail configuration

3. System mail name must have two words separated by dot (this is email domain name 

    mail sender uses to send email - not necessarily it should exist) Example:

    test.test or rainbeats.com or ubuntuserver.com

4. edit: /etc/postfix/main.cf

  update the line:

   old: inet_interfaces = all

   new: inet_interfaces = localhost 

5. Restart mail service: service postfix restart
