What algorithm is needed when setting up your mail server?

Question

Mail server

There is a domain name, a static IP, a server running Ubuntu Server 16.04. It is required to organize your own mail server, with access to mail through the web interface (Roundcube?) and through mail clients. What sequence of steps should be taken to get the desired result - your personal mail? The simplest option, of course, is to use the same PDD from Yandex, but I want to practice on my own server in order to understand that it all works.

Answer 1

Put bind (your dns), put postfix (or exim, they are more or less simple) + dovecot (mail deliverer) + spamassassin + ClamAV There
will be plenty of training.
There are a lot of articles on the topic of installation.
1. Set up Bind (IN A, MX)
2. Register your NS (nameserver) at the registrar
3. Set up postfix (or exim) + dovecot (antivirus and spam cutter can then be screwed)
4. Wait for the dns cache update and test your server on the subject of the passage of letters.
This is if on your fingers) You can play around with RoundCube, but I would start with this.
