How to choose a complete email solution?

Question

linux

Please advise a good set of packages or lxd/docker container for a mail server on Ubuntu Server 17.10 in an LXD container that is really easy to install and not too hard to set up/maintain. You need a comprehensive solution, the web interface is optional (but the web admin is very desirable). For a small load
I often came across recommendations to use mailcow-dockerized, but it was not possible to start this container on Ubuntu Server 17.10 due to nothing saying access errors in the process of deploying the contents of the container, despite everything being done according to their instructions, in a privileged LXC container and through sudo .. (in the end, we tried it in every way, nothing helps).

Answer 1

Perhaps many will not agree with me, but the soap in the docker is a perversion. However, the docker itself is still a perversion, but it's not really about him.
Setting up a fully functional mail server is not a trivial task. Tailor it to your needs/wishlist entertainment for the long term. Another mail server is a lot of software packages compiled in the name of the "Great Purpose".
Do you want a ready-made solution in a container?
Perhaps with such approach to stop on MS Exchange? However, he will also have to suffer.
Joking aside, can you delegate the server to Yandex? Everything is simple and reliable there. Paranoia about the fact that your letters are no longer yours is only partly justified. But it is quite a workable complex solution.
I have a mail server postfix + dovecot + PostgreSQL + SpamAssassin + greylist + RoundCube + RainLoop.... Well, and some other little things, including a sieve, DKIM, and something else.
Do you want to download the container and get everything at once :)

Answer 2

Actually, it's a good question. I remember in recent times OpenVZ on Proxmox - it was enough to download a ready-made template directly from the web interface with everything preinstalled. And set up. Now, in theory, it should be like this: you are looking for a ready-made docker. Regarding MS Exchange, I don't know how it compares to "Postfix + dovecot + PostgreSQL + SpamAssassin + greylist + RoundCube + RainLoop", but then I'll offer IBM Domino server for a change. This is such a combine that works both as a mail, and as a web, and as a database server. Well, this is a bit offtopic. Look towards Zimbra ?

Answer 3

It's not difficult to set up and actually install iredmail
There is a docker , but it seems to be outdated.

Answer 4

ZENTYAL , AltLinux
iredmail - here you must first roll the axis

Answer 5

HighMan scared me, especially the blacklisting moment, and I've moved to Mail.ru for business until I try some of the options.
Yandex turned out to be somehow unfriendly in the process of trying to transfer the domain, plus it does not offer two-factor authentication via SMS, only through an application that for some reason is not available on Windows Mobile and the code itself is not compatible with third-party applications of its generation. Some stupidity.
