Set up Mail Server (RoundCube webmail) on aaPanel + CloudHosting

A mail server is the computerized equivalent of your friendly neighborhood mailman. Every email that is sent passes through a series of mail servers along its way to its intended recipient.
Although it may seem like a message is sent instantly – zipping from one PC to another in the blink of an eye – the reality is that a complex series of transfers take place.
Without this series of mail servers, you would only be able to send emails to people whose email address domains matched your own — i.e., you could only send messages from one example.com account to another example.com account.
