Tutorial: How to install vSMTP on OpenBSD

In this tutorial, we will go through the steps to install vSMTP on OpenBSD. vSMTP is a simple and easy-to-use mail transfer agent that allows you to send and receive email messages. The installation process should take no more than a few minutes.

Prerequisites

Before we begin, you will need the following:

  • Access to an OpenBSD server
  • Basic knowledge of the command line

Step 1: Download vSMTP

Firstly, let's download the latest version of the vSMTP software from the Viridit website. We can do this by running the following command in the terminal:

$ ftp https://viridit.com/vsmtp-mail-transfer-agent/vsmtp-X.X.X.tar.gz

Replace "X.X.X" with the latest version number available on the website.

Step 2: Extract the files

Once the file has finished downloading, extract the contents of the package by running the following command:

$ tar -zxvf vsmtp-X.X.X.tar.gz

This should create a new folder called vsmtp-X.X.X, where "X.X.X" is the version number you downloaded.

Step 3: Install vSMTP

Now that we have the vSMTP files, it's time to install it. We can do this by running the following command:

$ cd vsmtp-X.X.X
$ make install

This command will compile and install the vSMTP software on your OpenBSD machine.

Step 4: Configure vSMTP

After installation, we need to configure vSMTP to work with our email system. We can do this by editing the vsmtp.conf file located in the /etc directory:

$ sudo vi /etc/vsmtp.conf

In this file, you can adjust the following settings:

  • hostname: The hostname of your OpenBSD machine
  • domain: The domain of your email system
  • maildrop: The directory where emails are stored
  • smtpout: The SMTP server address for outgoing emails

Once you've made the necessary changes, save the file and exit the text editor.

Step 5: Start vSMTP

Finally, we need to start vSMTP to begin sending and receiving emails. We can do this by running the command:

$ sudo /etc/rc.d/vsmtp start

If everything is configured correctly, vSMTP should start up without any issues.

Conclusion

That's it! You've successfully installed and configured vSMTP on your OpenBSD machine. Now you can begin sending and receiving emails with ease.
