How to Install MailHog on OpenBSD

MailHog is an email testing tool that allows you to catch emails sent from your application without sending them to real recipients. This tutorial will guide you through the process of installing MailHog on OpenBSD.

Prerequisites

Before starting the MailHog installation process, ensure that the following prerequisites are met:

• A running OpenBSD instance
• A package manager such as OpenBSD's pkg_add

Installation process

Follow the steps below to install MailHog on OpenBSD:

1. Open a terminal window on your OpenBSD instance.

2. Retrieve the MailHog binary from the official repository using the following command:

   $ fetch https://github.com/mailhog/MailHog/releases/download/v1.0.0/MailHog_openbsd_amd64
   

   This command will download the MailHog binary for OpenBSD in the current directory.

3. Grant executable permissions to the downloaded binary using the chmod command:

   $ chmod +x MailHog_openbsd_amd64
   

4. Run the MailHog binary on a specific port, for example, port 1025:

   $ ./MailHog_openbsd_amd64 -ui-bind-addr=":8025" -smtp-bind-addr=":1025"
   

   Now MailHog will be listening to your OpenBSD system on the specified port waiting for any email sent to it.

Verify MailHog installation

To verify that MailHog is installed correctly, follow these steps:

1. In your web browser, enter the IP address or name of your OpenBSD instance and the port number where MailHog is listening, for example:

   http://192.168.1.100:8025/
   

2. You will see the MailHog Web UI interface where you can see any email that was sent to MailHog.

3. Test MailHog by sending an email from your local machine to port 1025 on your OpenBSD instance. You can use the telnet command to simulate the email sending process:

   $ telnet 192.168.1.100 1025
   

   Then, type the following commands, replacing the email address and other details with your own custom details:

   Trying 192.168.1.100...
   Connected to 192.168.1.100.
   Escape character is '^]'.
   220  mailhog.example.com ESMTP MailHog
   EHLO mail.test.com
   MAIL FROM:<name@test.com>
   RCPT TO:<your-email@example.com>
   DATA
   Subject: Test Email
   From: name@test.com
   To: your-email@example.com
   
   This is a test email from MailHog.
   .
   QUIT
   

4. In your web browser, refresh the MailHog Web UI page (or press F5 on your keyboard) to see the details of the email.

Congratulations! You have successfully installed MailHog on your OpenBSD instance.
