How to make a mail server for a website?

Question

Mail server

I would like to know the recommendations and best practices on how to make mail on the same domain as the site. Do you use docker (for example, if there is more than one site on the server)? How it is better to organize the interface of mail for users - to be connected by clients like Outlook or to raise a web the interface any?
If anything, the main site on django.

Answer 1

Previously, the fashionable word "clouds" was shoved everywhere.
Now everywhere they shove the fashionable word "docker", "kuber", "schmuber"...
If you don't understand, Yandex mail for a domain is really the best for you :)
And normal people, without straining, put sendmail on the server parallel to the web (apache or nginx) and dovecot (well, a web face, if you really need it) - and the mail goes ... For greater security, you can spread it all over a couple of virtual machines.

Answer 2

Hello!
Of course, there are options to make mail yourself, for example https://habr.com/ru/post/539736/
But there are many ready-made solutions, and the same Yandex Connect, although it has a number of glitches, and Mile ru for business, two free and dimensionless options, there are paid ones from Google, Yahoo, Microsoft. There are options in Switzerland, for those who do not like the free access of law enforcement agencies to our mails, and the same American ones to theirs, ProtonMail, Infomaniak, Migadu

Answer 3

best practics

best practices are what you know and can maintain without too much pressure.
For me, "best practice" is "all your own". Your hardware, your mailer, your mailing service, and so on.
But if you are limited in knowledge, budget, and other resources, you need to use third-party services and not bother.
In the end, everyone works for the result.
