Sendmail is a popular email transfer agent that allows you to send and receive email messages. In this tutorial, we will walk you through the process of installing Sendmail on FreeBSD Latest.
Before installing Sendmail, ensure that you have:
Before installing any new software on your FreeBSD machine, it is recommended to update the system to its latest version using the following command:
$ sudo freebsd-update fetch install
This will update your FreeBSD operating system to the latest version with any security patches and bug fixes.
Download the latest version of Sendmail from Proofpoint.
Extract the downloaded file into a temporary directory using the below command:
$ tar xzvf sendmail-file-name.tar.gz -C /tmp/
Navigate to the extracted directory:
$ cd /tmp/sendmail-version/
Compile the Sendmail source code:
$ make
Install Sendmail binaries and configuration files:
$ sudo make install
The Sendmail configuration file is located in /etc/mail/ directory.
Firstly, make a backup of the existing Sendmail configuration file:
$ sudo cp /etc/mail/sendmail.cf /etc/mail/sendmail.cf.bak
Now configure Sendmail using the below command:
$ sudo sh /etc/mail/makemap hash /etc/mail/aliases < /etc/mail/aliases
Edit the Sendmail configuration file /etc/mail/sendmail.cf by setting the following parameters:
# My domain name
Djexample.com
# Define local email domain
Fw/etc/mail/local-host-names
# Smart relay host (replace server with your SMTP server name)
DS server
Note that you should replace example.com and server with your own domain name and SMTP server name, respectively.
Once done with making changes, restart the Sendmail service:
$ sudo service sendmail restart
You have successfully installed and configured Sendmail on your FreeBSD Latest server. You can now send and receive email messages using your own domain name.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
