How to Install Sendmail on Void Linux

Sendmail is a popular open-source email solution that allows you to send and receive emails on your server. In this tutorial, we will show you how to install Sendmail on Void Linux.

Prerequisites

• A server running Void Linux
• A user with sudo privileges

Step 1: Update System

Before installing any new package, it's always a good idea to update the system. Run the following command:

sudo xbps-install -Su

Step 2: Install Sendmail

To install Sendmail on Void Linux, run the following command:

sudo xbps-install sendmail

Step 3: Configure Sendmail

Once Sendmail is installed, it must be configured. Open the Sendmail configuration file using your favorite text editor:

sudo vi /etc/mail/sendmail.mc

Add the following lines at the bottom of the file:

FEATURE(`access_db')dnl
DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl

Save and close the file. Then, run the following command to update the Sendmail configuration:

sudo m4 /etc/mail/sendmail.mc > /etc/mail/sendmail.cf

Finally, restart Sendmail to apply the changes with the following command:

sudo service sendmail restart

Step 4: Test Sendmail

To test Sendmail, use the following command:

echo "hello" | sendmail <your_email_address>

Replace <your_email_address> with the email address you want to send the test email to. If you receive the test email successfully, then Sendmail is working properly.

Congratulations! You have successfully installed and configured Sendmail on your Void Linux server.
