Maildrop is an open-source mail filtering and delivery tool that is widely used by email administrators. In this tutorial, we will explain how to install Maildrop on Fedora CoreOS Latest.
Before we start with the Maildrop installation, let's update our Fedora CoreOS system to make sure that all the packages and dependencies are up-to-date. Use the following command to update the system:
sudo rpm-ostree update
To install Maildrop on Fedora CoreOS, we need to first install the RPM Fusion repository. RPM Fusion provides various RPM packages that are usually not found in Fedora's official repository. Run the following command to add RPM Fusion on your Fedora CoreOS.
sudo rpm-ostree install https://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
We can now install Maildrop by running the following command:
sudo dnf install maildrop
Now that Maildrop is installed, we need to configure it to start using it. Maildrop uses a configuration file located in /etc/maildroprc. Open the file in your preferred text editor:
sudo nano /etc/maildroprc
By default, the configuration file is empty. You can add maildrop rules to filter and deliver email based on sender, recipient, subject, and content. Here's an example rule that delivers all emails from a specific sender to a mailbox:
if ( /^From:.*specific\@sender.com/:h ) {
deliver "/var/mail/spool/specific"
}
Once you're done with the configuration, save and close the file.
To start the Maildrop server, you can use the following command:
sudo systemctl start maildrop
If you want to start Maildrop at boot time, run the following command to enable the service:
sudo systemctl enable maildrop
In this tutorial, we've explained how to install and configure Maildrop on Fedora CoreOS Latest. You can now start using Maildrop to filter and deliver incoming email to your mailbox.
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!
