5.3.2. Postfix

To configure postfix correctly, run the following commands as root.

Create a symbolic link allowing postfix to run the notification enqueuer with the following command:
```
# ln -s /usr/bin/ack_enqueuer.pl /etc/smrsh/.
```
Edit the /etc/aliases file on the mail server and add the following line:
```
rogerthat01: "| /etc/smrsh/ack_enqueuer.pl"
```
Ensure the following line exists in your /etc/postfix/main.cf file and change:
```
inet_interfaces = all
```
Process the alias with the following command:
```
# newaliases
```
Restart postfix:
```
# service postfix restart
```
