Postmap All Postfix Config Files

We will need to postmap all postfix config files to make sure everything is working smoothly.

Postmap All Postfix Config

cd /etc/postfix
postmap virtual
postmap access
postmap canonical
postmap relocated
postmap sender_canonical
postmap transport

Note:

when you postmap the postfix config file. there will be 1 or 2 files not found.
you can simply touch a blank files and postmap it.
if everything goes smoothly when you postmap those config, please skip the example below.

Example :

touch /etc/postfix/sender_canonical
postmap /etc/postfix/sender_canonical
