Courier MTA is an open source mail transfer agent that supports IMAP, POP3, SMTP, and webmail. It is a lightweight and easy-to-use mail server with various features and configuration options.
Before starting the installation process, make sure you have the following:
The first step is to update the NetBSD system to ensure that all packages are up to date. To update the system, run the following command:

Now, it's time to configure the Courier MTA package to use it as a mail server. You can configure it using the configuration files located in the /usr/pkg/etc/courier directory.
The main configuration file is the esmtpd file, which controls the SMTP server. You can edit this file using your preferred text editor:
# vi /usr/pkg/etc/courier/esmtpd
You can customize various properties, such as SMTP port number, message size limit, TLS settings, etc., according to your requirements.
After configuring Courier MTA, start the service using the following command:
# /usr/pkg/etc/rc.d/courier start
It will start the Courier MTA package and make it available to send and receive emails.
