OpenSMTPD is a modern mail server that is easy to use, secure, and flexible. It is a popular alternative to other mail servers like Postfix and Sendmail. In this tutorial, we will cover how to install OpenSMTPD on FreeBSD Latest.
Before installing OpenSMTPD, you should update the FreeBSD system by running the following command:
sudo pkg update && sudo pkg upgrade
This command will ensure that FreeBSD's package manager is up to date and all system packages are updated to the latest version.
To install OpenSMTPD on FreeBSD Latest, run the following command:
sudo pkg install opensmtpd
This command will download and install OpenSMTPD along with any necessary dependencies.
By default, OpenSMTPD is not configured to send or receive email. To configure OpenSMTPD, you need to edit the smtpd.conf file located in /usr/local/etc/opensmtpd/.
sudo nano /usr/local/etc/opensmtpd/smtpd.conf
Add the following contents to the file:
table aliases file:/etc/mail/aliases
listen on all
listen on ::
action "local" mbox
match from any for domain <localhost> action "local"
match from any for local_parts match action "local"
The above configuration sets up OpenSMTPD to listen on all interfaces and receives emails for the local domain. The table aliases line specifies the location of the mail aliases file. You can change this to a different file or omit it altogether if you don't need it.
To start OpenSMTPD, run the following command:
sudo service smtpd start
You can also enable OpenSMTPD to start on boot by running the following command:
sudo sysrc smtpd_enable=YES
To test OpenSMTPD, you can use the mail command to send an email to a local user. For example:
echo "Test email" | mail -s "Test Subject" testuser
This will send an email with the subject "Test Subject" to the local user "testuser". You can then check if the email has been delivered by running the following command:
sudo tail -f /var/log/maillog
This will show the latest log entries for OpenSMTPD. If the email was delivered successfully, you should see a log message indicating that the email was delivered to the local mailbox.
Now you know how to install OpenSMTPD on FreeBSD Latest. OpenSMTPD is a powerful and easy-to-use mail server that can handle your email needs with ease. If you need further information, you can refer to the official OpenSMTPD documentation.
