Cyrus IMAP is an open-source email server software that allows users to access their emails from multiple devices via the Internet Mail Access Protocol (IMAP). In this tutorial, we will explain how you can install Cyrus IMAP on OpenBSD – a secure and free operating system.
Before you start the installation process, make sure that you have:
It is always a good practice to update your system before installing new software. You can update your OpenBSD system by running the following command:
sudo syspatch
This command will check for available patches and update any vulnerable packages on your system.
Cyrus IMAP is available in the OpenBSD package collection, which means you can easily install it using the package manager. To install Cyrus IMAP, run the following command:
sudo pkg_add cyrus-imapd
This command will download and install the Cyrus IMAP package and its dependencies on your OpenBSD system.
Note: If the package manager is not installed on your OpenBSD system, you can install it by running the following command:
sudo pkg_add pkg_mgr
Once the installation is complete, you need to configure Cyrus IMAP by editing its configuration file. You can find the configuration file at /etc/imapd.conf. You can use any text editor of your choice to edit the configuration file. For example, to edit the file using the vi editor, run the following command:
sudo vi /etc/imapd.conf
You can now configure Cyrus IMAP according to your requirements. Here are some basic configurations you can make:
servername directive.partition directive.sasl_mech_list directive.sasl_pwcheck_method and sasl_userdb directives.You can find more information on how to configure Cyrus IMAP in the official documentation at https://www.cyrusimap.org/docs/.
Once you have configured Cyrus IMAP, you can start the service by running the following command:
sudo /etc/rc.d/imapd start
This command will start the Cyrus IMAP service and enable it to start automatically at boot time.
To verify that Cyrus IMAP is installed and running correctly, you can use the telnet command to connect to the IMAP server. Run the following command to open a telnet session to the IMAP server:
telnet localhost 143
If Cyrus IMAP is running correctly, you should see a greeting message from the server. You can test further by logging in and checking your mailbox.
In this tutorial, we have shown you how to install and configure Cyrus IMAP on OpenBSD. Once you have Cyrus IMAP installed, you can use it to host your own email server, access your emails from multiple devices, and collaborate with your team.
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!
