When you decide to set up your own mail server, the first thing that comes to mind is reliability. You need a tool that can handle the email traffic, won’t crash at the worst possible moment, and won’t trap you in endless complicated configurations. One such tool is Exim4.
Exim4 is not just another mail-sending program. It’s a reliable mail transfer agent (MTA) that can receive emails, route them to the right recipients, and send them further. It supports encryption, filtering, connection to external SMTP servers, direct mail reception, and custom processing according to your needs.
Why Exim? Because it’s flexible. You can tailor it for any task — whether it’s a small home server or a large mail service with thousands of users. The key is not to be afraid of the settings. And here we’ll show you how to configure it without unnecessary pain.
