How to install Exim on FreeBSD Latest

Exim is a mail transfer agent (MTA) used on Unix-like operating systems. In this tutorial, we will cover the steps required to install Exim on FreeBSD Latest.

Prerequisites

Before proceeding with the installation, make sure that you have root access to the FreeBSD Latest system.

Step 1: Update the package repository

The first step is to update the package repository using the following command:

pkg update

This command will check for the latest available packages and update the package repository accordingly.

Step 2: Install Exim

Next, we will install Exim using the following command:

pkg install exim

This command will download and install Exim and all of its dependencies.

Step 3: Configure Exim

Once the installation is complete, we need to configure Exim. The main configuration file for Exim is located at /usr/local/etc/exim.conf.

We can either modify this file directly or create a new configuration file in a different location and specify it using the -C option while running Exim. In this tutorial, we will modify the existing configuration file.

Open the configuration file using a text editor:

ee /usr/local/etc/exim.conf

Configure Exim according to your requirements. Some common configuration options include:

• dc_eximconfig_configtype: This option specifies the type of configuration. You can set it to internet for a typical internet-facing server.
• dc_local_interfaces: This option specifies the IP addresses that Exim should listen on for incoming connections.
• dc_readhost: This option specifies the hostname of the server.
• dc_relay_nets: This option specifies the IP addresses that are allowed to relay mail through Exim. By default, Exim will only allow localhost to relay mail.

Here's an example configuration:

# /usr/local/etc/exim.conf

dc_eximconfig_configtype='internet'
dc_local_interfaces='127.0.0.1 ; ::1'
dc_readhost='example.com'
dc_relay_nets=''

# Add more configuration options as required

Once you have configured Exim, save the changes and exit the text editor.

Step 4: Test Exim

To test Exim, we will send a test email using the mail command:

echo "My test email" | mail -s "Test email" recipient@example.com

Replace recipient@example.com with your own email address.

If everything is configured correctly, you should receive the test email.

Conclusion

In this tutorial, we covered the steps required to install and configure Exim on FreeBSD Latest. You can now use Exim to send and receive emails on your FreeBSD Latest system.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
