Which is better? Microsoft Exchange 2016 or Linux-based SMTP Servers?

[Turritopsis Dohrnii Teo En Ming]

Good evening from Singapore,

I am torn between deploying Microsoft Exchange 2016 and Linux-based
SMTP servers like sendmail, postfix, qmail and exim.

Relative ease of installation and configuration is an important
consideration factor.

Microsoft Exchange 2016, Domain Controller, and Active Directory are
relatively easy to install and configure. Linux-based SMTP servers are
extremely difficult to install and configure and of course, extremely
time-consuming.

One of the features of Microsoft Exchange 2016 is that you can create
additional folders on your Inbox in the server (server-side). Can
Linux-based SMTP servers do that?

Does Exchange 2016 offer more user-friendly features or Linux-based
SMTP servers?

Besides the above considerations, how about security? Traditionally,
Linux is far more secure than Windows.

Judging by security, Linux-based SMTP servers ought to have a higher percentage of the market share?

Finally, I can only use Windows Server 2016 Standard Evaluation Copy FREE for a period of 3 years MAXIMUM. But I can use Linux servers and Mail Transport Agents (MTA) FREE perpetually.

Please advise.

Thank you very much.
