• You are note able to restart / start postfix and getting the below error.

fatal: parameter inet_interfaces: no local interface found for ::1

Solution

• • Edit the file /etc/postfix/main.cf
    vim /etc/postfix/main.cf

• • search for the line
    inet_interfaces = all
  • And change it to:
    inet_interfaces = 127.0.0.1, 10.10.11.12
    10.10.11.12 is your server local IP address
  • :wq! Save and exit

• restart postfix.
  service postfix restart

• Updates:
  • • If you dont want to use IPv6 on the server, you can simply comment the below line from /etc/hosts
      ::1
