IRedMail vs Microsoft Exchange vs hmailserver?

Question

hMailServer

Now there is hmailserver on Windows 10 Pro Education 1909. I'm looking forward to Windows 10 20H1, where there will be a full-fledged WSL 2, where I plan to put iRedMail.
But first I want to consult with knowledgeable people and gurus. What is better to use?!
1. Leave HmailServer:
Everything is perfect in principle, but the functionality is a bit weak and in case of some integrations or extensions, everything will have to be done with JavaScript. And everything is so great!
2. Use Microsoft Exchenge:
Ideal, but it uses its own unique protocol and to use SMTP, IMAP, POP3 you need to install crutches and bridges. Plus, you need a domain network, but I can’t use Windows Server, because of the Gigabyte AMD Radeon video card, HP LaserJet 1100 (MS) printer and Mustek Bear Paw 2400CU Plus scanner!
3. IRedMail:
It does not have the disadvantages of Microsoft Exchange Server and has a number of advantages. For example, you can use an OpenLDAP database instead of MySQL, which allows you to use a cloud notebook and a remote calendar of events. But it requires full Linux. Ports like WSL and Cygwin will not work, only WSL 2.
Please tell me which of these should be used?!

Answer 1

Leave HMailServer.

An ideal option, but it uses its own unique protocol and in order to use SMTP, IMAP, POP3 you need to install crutches and bridges

I make allowances for your age, but what a mess you have in your head.
PS
Exchange will not give you such flexibility, it will eat up all your resources. SMTP/IMAP/POP are the native protocols of Exchange.
iRedMail is a Postfix wrapper, just like Zimbra.
PPS
Install the latest VirtualBox or enable Hyper-V on your ten and deploy Linux cars, as you have already been advised. Forget about these crutches like WSL.

Answer 2

4. Stop torturing WSL and master virtualization/containerization. And in it already twist what you like.
