Checking the version of your Exim mail server is a common and important task for system administrators and users. Exim is a popular open-source mail transfer agent (MTA) used to send, receive, and manage emails on many Unix-like systems. Knowing the version of your Exim server helps you determine if there are available updates, security patches, or new features you can take advantage of. It also allows you to troubleshoot any issues more effectively.
There are several ways to check the version of your Exim mail server. One common method is to use the command line. SSH into your server and type the following command:
exim -bv
This command will output the version of Exim installed on your system. For example:
Exim version 4.96.2
You can also check the version of Exim by looking at the configuration file. The main configuration file for Exim is usually located at /etc/exim.conf. Open the file and look for the line that starts with version =. The value after the equals sign is the version of Exim.
If you are using a control panel like cPanel or Plesk, you may be able to find the version of Exim in the control panel’s interface. For example, in cPanel, you can go to the Email section and click on Exim Configuration Manager. The version of Exim will be displayed at the top of the page.
Keeping your Exim mail server up to date is important for security and performance reasons. Regularly checking the version of Exim and applying updates as needed will help to ensure that your mail server is running smoothly and securely.
